Description
本新型是有關於一種供電控制裝置，特別是指一種感應式供電控制裝置。The present invention relates to a power supply control device, and more particularly to an inductive power supply control device.
參閱圖1，現有的感應式供電控制裝置1可利用例如熱感應方式來控制例如一電燈2的供電，並包含一整流電路11、一驅動電壓產生電路12、一工作電壓產生電路13、一開關電路14、一控制電路15及一紅外線感測器16。Referring to FIG. 1 , the conventional inductive power supply control device 1 can control, for example, a power supply of the electric lamp 2 by using a thermal induction method, and includes a rectifier circuit 11 , a driving voltage generating circuit 12 , an operating voltage generating circuit 13 , and a switch. The circuit 14, a control circuit 15 and an infrared sensor 16.
該降壓整流電路11用於將由一交流電源3所提供的交流電壓，例如，市電(即，110V或220V的交流電壓)降壓並整流以輸出一直流電壓。The step-down rectifier circuit 11 is for stepping down and rectifying an AC voltage supplied from an AC power source 3, for example, a commercial power (ie, an AC voltage of 110 V or 220 V) to output a DC voltage.
該驅動電壓產生電路12電連接該降壓整流電路11用以接收該直流電壓，並根據該直流電壓產生一小於該直流電壓的驅動電壓。該驅動電壓是要用來作為驅動該開關電路14之用。The driving voltage generating circuit 12 is electrically connected to the buck rectifier circuit 11 for receiving the DC voltage, and generates a driving voltage smaller than the DC voltage according to the DC voltage. This driving voltage is used to drive the switching circuit 14.
該工作電壓產生電路13電連接該驅動電壓產生電路12用以接收該驅動電壓，並根據該驅動電壓產生一小於該驅動電壓的工作電壓。該工作電壓是要用來供應該控制電路15運作時所需之電力。The operating voltage generating circuit 13 is electrically connected to the driving voltage generating circuit 12 for receiving the driving voltage, and generates an operating voltage smaller than the driving voltage according to the driving voltage. This operating voltage is used to supply the power required to operate the control circuit 15.
該紅外線感測器16電連接該控制電路15，並利用紅外線感測方式(即，熱感應方式)感測其所在感測範圍內是否有物件(例如人、或車輛)進入。在運作上，該紅外線感測器16僅在感測到有物件進入該感測範圍時，才輸出一觸發信號至該控制電路15。The infrared sensor 16 is electrically connected to the control circuit 15 and senses whether an object (for example, a person or a vehicle) enters within the sensing range in which it is located by using an infrared sensing method (ie, a thermal sensing method). In operation, the infrared sensor 16 outputs a trigger signal to the control circuit 15 only when it senses that an object enters the sensing range.
該控制電路15電連接該工作電壓產生電路13用以接收該工作電壓，且電連接該開關電路14，並在接收到來自該紅線感測器16的該觸發信號時，回應於該觸發信號而輸出一供電控制信號至該開關電路14。The control circuit 15 is electrically connected to the operating voltage generating circuit 13 for receiving the operating voltage, and is electrically connected to the switching circuit 14, and is responsive to the trigger signal when receiving the trigger signal from the red line sensor 16. A power supply control signal is output to the switch circuit 14.
該開關電路14電連接該驅動電壓產生電路12與該工作電壓產生電路13之間的一共同節點N以接收該驅動電壓，並且還電連接在該交流電源3及該電燈2之間。該開關電路14在接收到來自於該控制電路15的該供電控制信號時，回應於該供電控制信號而建立該交流電源3與該電燈2之間的電連接，在此情況下，來自於該交流電源3的該交流電壓能經由該開關電路14供應至該電燈2，於是該電燈2處於發光狀態。相反地，若該開關電路14未接收到來自該控制電路15的該供電控制信號時，該開關電路14將使該交流電源3與該電燈2之間保持斷路，以致來自於該交流電源3的該交流電壓無法供應至該電燈2，於是該電燈2將保持在不發光狀態。The switch circuit 14 is electrically connected to a common node N between the driving voltage generating circuit 12 and the operating voltage generating circuit 13 to receive the driving voltage, and is also electrically connected between the alternating current power source 3 and the electric lamp 2. The switch circuit 14, upon receiving the power supply control signal from the control circuit 15, establishes an electrical connection between the AC power source 3 and the lamp 2 in response to the power supply control signal, in which case, from the The AC voltage of the AC power source 3 can be supplied to the lamp 2 via the switch circuit 14, so that the lamp 2 is in a light-emitting state. Conversely, if the switch circuit 14 does not receive the power supply control signal from the control circuit 15, the switch circuit 14 will keep the AC power source 3 and the lamp 2 open, so that the AC power source 3 is connected. The AC voltage cannot be supplied to the lamp 2, so the lamp 2 will remain in a non-illuminated state.
在使用時，於該感測範圍內無任何物件進入的期間，該感應式供電控制裝置1處於一待命狀態，而當該紅外線感測器16感測到有任一物件進入該感測範圍時，該感應式供電控制裝置1會從該待命狀態切換至一控制狀態。在待命狀態下，從該降壓整流電路11流出的電流僅有相對小的電流成分流入該工作電壓產生電路13，而其大部分的電流成分會經由該驅動電壓產生電路12的內部電子組件(圖未示)流至地；而在控制狀態時，該電流除了上述相對小的電流成分流入該工作電壓產生電路13外，還有另一電流成分會經由該開關電路14的內部電子組件流至地，而剩餘的電流成分才會經由該驅動電壓產生電路12的內部電子組件(圖未示)流至地。In use, the inductive power supply control device 1 is in a standby state during the period in which no object enters within the sensing range, and when the infrared sensor 16 senses that any object enters the sensing range The inductive power supply control device 1 switches from the standby state to a control state. In the standby state, only a relatively small current component flows from the step-down rectifier circuit 11 into the operating voltage generating circuit 13, and most of its current component passes through the internal electronic components of the driving voltage generating circuit 12 ( The figure is not shown) flowing to the ground; and in the control state, the current flows into the operating voltage generating circuit 13 in addition to the relatively small current component, and another current component flows to the internal electronic component of the switching circuit 14 to The remaining current component flows to the ground via the internal electronic components (not shown) of the driving voltage generating circuit 12.
然而，值得注意的是，若該感應式供電控制裝置1在長時間處於該待命狀態的情況下，由於該電流的大部分電流成分流經該驅動電壓產生電路12，如此將導致該驅動電壓產生電路12的內部電子組件因長時間處於發熱狀態而升高溫度，因而加速內部電子組件的劣化而致使其壽命縮短。However, it is worth noting that if the inductive power supply control device 1 is in the standby state for a long time, since most of the current component of the current flows through the driving voltage generating circuit 12, the driving voltage is generated. The internal electronic components of the circuit 12 rise in temperature due to prolonged heating, thereby accelerating the degradation of the internal electronic components and shortening their lifetime.
因此，上述現有的感應式供電控制裝置1仍存在有很大的改良空間。Therefore, the above-described conventional inductive power supply control device 1 still has a large room for improvement.
因此，本新型之目的，即在提供一種感應式供電控制裝置，其能減緩現有技術的至少一缺點。Accordingly, it is an object of the present invention to provide an inductive power supply control device that mitigates at least one of the disadvantages of the prior art.
於是，本新型一種感應式供電控制裝置，用於控制一電子裝置的供電，並包含一降壓整流電路、一驅動電壓產生電路、一工作電壓產生電路、一開關電路、一分流電路、感測單元、及一控制單元。Therefore, the inductive power supply control device is used for controlling the power supply of an electronic device, and comprises a step-down rectifier circuit, a driving voltage generating circuit, an operating voltage generating circuit, a switching circuit, a shunt circuit, and sensing. Unit, and a control unit.
該降壓整流電路適於將來自於一交流電源的交流電壓進行降壓並整流處理後，輸出一直流電壓並允許一定電流流出。The step-down rectifier circuit is adapted to step down and rectify the AC voltage from an AC power source, and then output a DC voltage and allow a certain current to flow out.
該驅動電壓產生電路電連接該降壓整流電路以接收該直流電壓，並根據該直流電壓產生一小於該直流電壓的驅動電壓。The driving voltage generating circuit is electrically connected to the buck rectifier circuit to receive the DC voltage, and generates a driving voltage smaller than the DC voltage according to the DC voltage.
該工作電壓產生電路電連接該驅動電壓產生電路以接收該驅動電壓，並根據該驅動電壓產生一小於該驅動電壓的工作電壓。The working voltage generating circuit is electrically connected to the driving voltage generating circuit to receive the driving voltage, and generates an operating voltage smaller than the driving voltage according to the driving voltage.
該開關電路電連接一在該驅動電壓產生電路與該工作電壓產生電路之間的共同節點以接收該驅動電壓，且還適於電連接該交流電源與該電子裝置，並具有一控制端。當該開關電路的該控制端接收到一供電控制信號時，該開關電路回應於該供電控制信號並根據該驅動電壓，建立該交流電源與該電子裝置之間的電連接，以致來自該交流電源的該交流電壓經由該開關電路供應至該電子裝置。當該開關電路的該控制端未接收到該供電控制信號時，該開關電路使該交流電源與該電此裝置之間維持斷路，以致來自交流電元的該交流電壓無法供應至該電子裝置。The switch circuit is electrically connected to a common node between the driving voltage generating circuit and the operating voltage generating circuit to receive the driving voltage, and is further adapted to electrically connect the alternating current power source and the electronic device, and has a control end. When the control terminal of the switch circuit receives a power supply control signal, the switch circuit responds to the power supply control signal and establishes an electrical connection between the AC power source and the electronic device according to the drive voltage, so as to be from the AC power source. The AC voltage is supplied to the electronic device via the switching circuit. When the control terminal of the switch circuit does not receive the power supply control signal, the switch circuit maintains an open circuit between the AC power source and the electric device, so that the AC voltage from the AC power element cannot be supplied to the electronic device.
該分流電路電連接該共同節點，且具有一控制端。當該分流電路的該控制端接收到一分流控制信號時，該分流電路回應於該分流控制信號而建立一在該共同節點與地之間的分流路徑。The shunt circuit is electrically connected to the common node and has a control end. When the control terminal of the shunt circuit receives a shunt control signal, the shunt circuit establishes a shunt path between the common node and the ground in response to the shunt control signal.
該感測單元具有一輸出端，且組配來利用熱感應方式或光感應方式感測其本身所處的一感測範圍內是否有物件進入，並在感測到該感測範圍內有物件進入時，經由該輸出端輸出一觸發信號。The sensing unit has an output end, and is configured to sense whether an object enters within a sensing range in which it is located by using a thermal sensing method or a light sensing method, and objects are detected within the sensing range. Upon entering, a trigger signal is output via the output.
該控制單元電連接該工作電壓產生電路以接收該工作電壓，且電連接該開關電路的該控制端、該分流電路的該控制端、及該感測單元的該輸出端。在未接收到來自該感測單元的該觸發信號的期間，該控制單元基於所接收的該工作電壓，通常操作在一斷電模式，且僅在接收到來自該感測單元的該觸發信號時，回應於該觸發信號而切換至一供電模式。The control unit is electrically connected to the operating voltage generating circuit to receive the operating voltage, and is electrically connected to the control end of the switching circuit, the control end of the shunt circuit, and the output end of the sensing unit. While not receiving the trigger signal from the sensing unit, the control unit generally operates in a power down mode based on the received operating voltage, and only when receiving the trigger signal from the sensing unit Switching to a power supply mode in response to the trigger signal.
該控制單元在操作於該斷電模式期間內，持續輸出該分流控制信號至該分流電路的該控制端，以致從該降壓整流電路流出的定電流的一電流成分經由該分流路徑流至地。The control unit continuously outputs the shunt control signal to the control terminal of the shunt circuit during operation of the power down mode, such that a current component of the constant current flowing from the buck rectifier circuit flows to the ground via the shunt path .
當該控制單元切換至該供電模式時，該控制單元於一預定時間期間輸出該供電控制信號至該開關電路的該控制端，以致該交流電壓於該預定時間期間被供應至該電子裝置。When the control unit switches to the power supply mode, the control unit outputs the power supply control signal to the control terminal of the switch circuit for a predetermined time period, so that the AC voltage is supplied to the electronic device during the predetermined time period.
本新型之功效在於：即使該控制單元長時間操作在該斷電模式(即，該感應式供電控制裝置長時間處於待命狀態)，透過該分流電路所提供的分流路徑，能使部分電流經由該分流路徑流至地，藉此相對地減少經由該驅動電壓產生電路流至地的電流大小，進而緩和該驅動電壓產生電路的升溫現象並延緩該驅動電壓產生電路的劣化以延長其壽命。The effect of the novel is that even if the control unit is operated in the power-off mode for a long time (that is, the inductive power supply control device is in a standby state for a long time), a part of the current can be transmitted through the shunt path provided by the shunt circuit. The shunt path flows to the ground, thereby relatively reducing the magnitude of the current flowing to the ground via the driving voltage generating circuit, thereby alleviating the temperature rise phenomenon of the driving voltage generating circuit and delaying the deterioration of the driving voltage generating circuit to prolong its life.
在本新型被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖2，本新型一種感應式供電控制裝置100係用於控制一電子裝置200(例如，電燈裝置，但不在此限)的供電，並包含一降壓整流電路10、一驅動電壓產生電路20、一工作電壓產生電路30、一開關電路40、一控制單元50、感測單元60、一輸入單元70、一指示單元80及一分流電路90。Referring to FIG. 2, an inductive power supply control device 100 is used for controlling power supply of an electronic device 200 (for example, an electric lamp device, but not limited thereto), and includes a buck rectifier circuit 10 and a driving voltage generating circuit 20 An operating voltage generating circuit 30, a switching circuit 40, a control unit 50, a sensing unit 60, an input unit 70, an indicating unit 80, and a shunt circuit 90.
該降壓整流電路10適於將來自於一交流電源300的交流電壓進行降壓並整流處理後輸出一直流電壓V dc。在本實施例中，該交流電源300例如為市電，而該交流電壓例如為110V或220V的交流電壓，但不以此例為限。此外，該降壓整流電路10例如包含一用於降壓的RC電路、及一用於全波整流的橋式整流電路(圖未示)，但不在此限。舉例來說，該降壓整流電路10能被設計來將110V的交流電壓降壓並整流後輸出例如約35V的直流電壓V dc，但不以此例為限。值得注意的是，該降壓整流電路10在輸出該直流電壓V dc時，允許一定電流I流出(見圖3)。 The step-down rectifier circuit 10 is adapted to step down and rectify the AC voltage from an AC power source 300 to output a DC voltage V dc . In this embodiment, the AC power source 300 is, for example, a commercial power source, and the AC voltage is, for example, an AC voltage of 110 V or 220 V, but is not limited thereto. In addition, the step-down rectifier circuit 10 includes, for example, an RC circuit for step-down and a bridge rectifier circuit (not shown) for full-wave rectification, but is not limited thereto. For example, the buck rectifier circuit 10 can be designed to step down and rectify an AC voltage of 110 V to output a DC voltage V dc of , for example, about 35 V, but is not limited thereto. It is worth noting that the buck rectifier circuit 10 allows a certain current I to flow when the DC voltage V dc is output (see FIG. 3).
該驅動電壓產生電路20電連接該降壓整流電路10以接收該直流電壓V dc，並根據該直流電壓V dc產生一小於該直流電壓V dc的驅動電壓V drive。再參閱圖3，在本實施例中，該驅動電壓產生電路20例如包含彼此串聯的一電阻器21及一稽納二極體22，但不在此限，其中該稽納二極體22的陰極與陽極分別電連接該電阻器21及地，並且該稽納二極體22的崩潰電壓作為該驅動電壓V drive。在本實施例中，該驅動電壓V drive是被設計來驅動該開關電路40之用。 The driving voltage generating circuit 20 is electrically connected to the step-down rectifying circuit 10 to receive the DC voltage V dc , and generates a driving voltage V drive smaller than the DC voltage V dc according to the DC voltage V dc . Referring to FIG. 3, in the embodiment, the driving voltage generating circuit 20 includes, for example, a resistor 21 and a gate diode 22 connected in series with each other, but not limited thereto, wherein the cathode of the Zener diode 22 is included. The resistor 21 and the ground are electrically connected to the anode, respectively, and the breakdown voltage of the arrester diode 22 is used as the driving voltage V drive . In the present embodiment, the driving voltage V drive is designed to drive the switching circuit 40.
該工作電壓產生電路40電連接該驅動電壓產生電路20以接收該驅動電壓V drive，並根據該驅動電壓V drive產生一小於該驅動電壓V drive的工作電壓V dd。在本實施例中，該工作電壓V dd例如為5V，但不在此限，且是要用來供應該控制單元50運作時所需之電力。 The operating voltage generating circuit 40 is electrically connected to the driving voltage generating circuit 20 to receive the driving voltage V drive , and generates an operating voltage V dd smaller than the driving voltage V drive according to the driving voltage V drive . In the present embodiment, the operating voltage V dd is, for example, 5V, but not limited thereto, and is used to supply the power required for the operation of the control unit 50.
該開關電路40電連接一在該驅動電壓產生電路20與該工作電壓產生電路30之間的共同節點N2以接收該驅動電壓V drive，且還適於電連接在該交流電源300與該電子裝置200之間，並具有一控制端41。當該開關電路40的該控制端41接收到一供電控制信號S2時(見圖4)，該開關電路40回應於該供電控制信號S2並根據該驅動電壓V drive，建立該交流電源300與該電子裝置200之間的電連接，以致來自該交流電源300的該交流電壓經由該開關電路40供應至該電子裝置200。當該開關電路40的該控制端41未接收到該供電控制信號S2時(見圖3)，該開關電路40使該交流電源300與該電子裝置200之間維持斷路，以致來自該交流電源300的該交流電壓無法供應至該電子裝置200。以下將詳細說明該開關電路40的組成及運作。 The switch circuit 40 is electrically connected to a common node N2 between the driving voltage generating circuit 20 and the operating voltage generating circuit 30 to receive the driving voltage V drive , and is further adapted to be electrically connected to the alternating current power source 300 and the electronic device. Between 200 and has a control terminal 41. When the control terminal 41 of the switch circuit 40 receives a power supply control signal S2 (see FIG. 4), the switch circuit 40 responds to the power supply control signal S2 and establishes the AC power source 300 according to the drive voltage V drive . The electrical connection between the electronic devices 200 is such that the AC voltage from the AC power source 300 is supplied to the electronic device 200 via the switch circuit 40. When the control terminal 41 of the switch circuit 40 does not receive the power supply control signal S2 (see FIG. 3), the switch circuit 40 maintains an open circuit between the AC power source 300 and the electronic device 200, so that the AC power source 300 is obtained. The AC voltage cannot be supplied to the electronic device 200. The composition and operation of the switch circuit 40 will be described in detail below.
再參閱圖3及圖4，在本實施例中，該開關電路40例如包含一開關元件43及一電磁閥42，但不以此例為限。更具體地，該電磁閥42具有一電連接該共用節點N2的第一端421、一第二端422，以及分別電連接該交流電源300及該電子裝置200的一第三端423及一第四端424，並例如包含一電連接在該第一端421與該第二端422之間的感應線圈425、及一電連接在該第三端423及該第四端424之間的磁感應開關426，但不以此例為限。該開關元件43可包含一電晶體(圖未示)，且電連接在該電磁閥42的該第二端422及地之間，並具有該開關電40路的控制端41。應注意的是，在本實施例中，如圖4所示，該開關元件43根據該供電控制信號S2導通。舉例來說，若該電磁閥42能被一24V的電壓驅動時，則該驅動電壓產生電路20的該稽納二極體22的崩潰電壓亦為24V，但不以此例為限；另一方面，若該開關元件43所包含的該電晶體為一npn電晶體時，則當該npn電晶體的閘極(作為該控制端41)接收到作為該供電控制信號S2的一高準位邏輯信號時，該npn電晶體導通，但不以此例為限。在此情況下，該感應線圈425與導通的該開關元件43共同構成一導通路徑P2，以致當該定電流I的一電流成分I 1流經由該導通路徑P2時，該磁感應開關426受到該感應線圈425所感應的磁場之驅動而導通，藉此建立該交流電源300與該電子裝置200之間的電連接，即，該電子裝置200由於能接收來自該交流電源300的交流電壓而處於供電狀態。反之，如圖3所示，若該開關元件43的該控制端41未接收到該供電控制信號S2，則該開關元件43保持不導通，在此情況下，由於圖4所示的該導通路徑P2尚未被建立，所以並無任何電流流經該感應線圈425，故該磁感應開關426因無感應磁場產生而保持不導通，致使該交流電源300與該電子裝置200之間保持斷路，即，該電子裝置200處於斷電狀態。然而，在其他實施例中，該稽納二極體22之規格僅須符合於該電磁閥42的規格，且該開關元件43亦可以其他的類型的電晶體來實施，而該供電控制信號S2可被設計成符合於該開關元件43之操作的其他邏輯信號。 Referring to FIG. 3 and FIG. 4 , in the embodiment, the switch circuit 40 includes a switching element 43 and a solenoid valve 42 , but is not limited thereto. More specifically, the solenoid valve 42 has a first end 421 and a second end 422 electrically connected to the common node N2, and a third end 423 and a first end electrically connected to the AC power source 300 and the electronic device 200, respectively. The fourth end 424 includes, for example, an inductive coil 425 electrically connected between the first end 421 and the second end 422, and a magnetic induction switch electrically connected between the third end 423 and the fourth end 424 426, but not limited to this example. The switching element 43 can include a transistor (not shown) and is electrically connected between the second end 422 of the solenoid valve 42 and the ground, and has a control end 41 of the switching circuit 40. It should be noted that in the present embodiment, as shown in FIG. 4, the switching element 43 is turned on according to the power supply control signal S2. For example, if the solenoid valve 42 can be driven by a voltage of 24V, the breakdown voltage of the gate diode 22 of the driving voltage generating circuit 20 is also 24V, but not limited to this example; In one aspect, if the transistor included in the switching element 43 is an npn transistor, when the gate of the npn transistor (as the control terminal 41) receives a high level logic as the power supply control signal S2 When the signal is applied, the npn transistor is turned on, but not limited to this example. In this case, the inductive coil 425 and the turned-on switching element 43 together form a conduction path P2, so that when a current component I 1 of the constant current I flows through the conduction path P2, the magnetic inductive switch 426 receives the induction. The driving of the magnetic field induced by the coil 425 is turned on, thereby establishing an electrical connection between the alternating current power source 300 and the electronic device 200, that is, the electronic device 200 is powered by receiving an alternating voltage from the alternating current power source 300. . On the contrary, as shown in FIG. 3, if the control terminal 41 of the switching element 43 does not receive the power supply control signal S2, the switching element 43 remains non-conductive, in this case, due to the conduction path shown in FIG. P2 has not been established yet, so that no current flows through the induction coil 425. Therefore, the magnetic induction switch 426 remains non-conductive due to the generation of no induced magnetic field, so that the AC power supply 300 and the electronic device 200 are kept open, that is, the The electronic device 200 is in a power down state. However, in other embodiments, the size of the arrester diode 22 only has to conform to the specifications of the solenoid valve 42, and the switching element 43 can also be implemented by other types of transistors, and the power supply control signal S2 Other logic signals can be designed to conform to the operation of the switching element 43.
該分流電路90電連接該共同節點N2，且具有一控制端91。還參閱圖3，當該分流電路90的該控制端91接收到一分流控制信號S1時，該分流電路90回應於該分流控制信號S1而建立一在該共同節點N2與地之間的分流路徑P1。在本實施例中，該分流電路90例如可以一具有該控制端91且電連接在該共同節點N2與地之間的開關元件來實施，但不以此例為限。另一方面，還參閱圖4，若該分流電路90的該控制端91未接收到該分流控制信號S2時，該開關元件不導通，因而無法建立如圖3的該分流路徑P1。The shunt circuit 90 is electrically connected to the common node N2 and has a control terminal 91. Referring to FIG. 3, when the control terminal 91 of the shunt circuit 90 receives a shunt control signal S1, the shunt circuit 90 establishes a shunt path between the common node N2 and the ground in response to the shunt control signal S1. P1. In this embodiment, the shunt circuit 90 can be implemented, for example, by a switching element having the control terminal 91 and electrically connected between the common node N2 and the ground, but is not limited thereto. On the other hand, referring to FIG. 4, if the control terminal 91 of the shunt circuit 90 does not receive the shunt control signal S2, the switching element is not turned on, and thus the shunt path P1 of FIG. 3 cannot be established.
該感測單元60具有一輸出端63，且組配來利用熱感應方式或光感應方式感測其本身所處的一感測範圍(圖未示)內是否有物件(例如，人體或其他生物體)進入，並在感測到該感測範圍內有物件進入時，經由該輸出端63輸出一觸發信號。在本實施例中，該感測單元60例如包含一能以熱感應方式感測物件的紅外線感測器61、及一能以光感應方式感測物件的光感測器62，但不在此限。The sensing unit 60 has an output end 63 and is configured to sense whether there is an object (for example, a human body or other living body) in a sensing range (not shown) in which it is located by means of thermal sensing or light sensing. When the object enters and senses that an object enters within the sensing range, a trigger signal is output via the output terminal 63. In this embodiment, the sensing unit 60 includes, for example, an infrared sensor 61 capable of sensing an object in a thermally inductive manner, and a photo sensor 62 capable of sensing the object in an optically inductive manner, but not limited thereto. .
該控制單元50電連接該工作電壓產生電路30以接收該工作電壓V dd，且電連接該開關電路40的該控制端41、該分流電路90的該控制端91、及該感測單元60的該輸出端63。在未接收到來自該感測單元60的該觸發信號的期間，該控制單元50基於所接收的該工作電壓V dd，通常操作在一斷電模式，且僅在接收到來自該感測單元的60該觸發信號時，回應於該觸發信號而切換至一供電模式。換言之，該感測單元60在未感測到任何物件進入該感測範圍的期間，該輸出端63將不會輸出該觸發信號，於是該控制單元50由於未接收到來自該感測單元60的該輸出端63的該驅動信號而操作在該斷電模式。 The control unit 50 is electrically connected to the operating voltage generating circuit 30 to receive the operating voltage V dd , and is electrically connected to the control terminal 41 of the switching circuit 40 , the control terminal 91 of the shunting circuit 90 , and the sensing unit 60 . The output 63. While the trigger signal from the sensing unit 60 is not received, the control unit 50 normally operates in a power down mode based on the received operating voltage V dd and only receives the sensing unit from the sensing unit. When the trigger signal is 60, it switches to a power supply mode in response to the trigger signal. In other words, the sensing unit 60 will not output the trigger signal during the period when the sensing unit 60 does not sense that any object enters the sensing range, and the control unit 50 does not receive the sensing unit 60 from the sensing unit 60. The drive signal of the output terminal 63 operates in the power down mode.
更明確地說，如圖3所示，該控制單元50在操作於該斷電模式期間內，持續輸出該分流控制信號S1至該分流電路90的該控制端91。在此情況下，(從該降壓整流電路流出的)該定電流I將被分成三個電流成分I drive，I 1，I 2，其中該電流成分I drive經由因崩潰而導通的該稽納二極體22流至地，該電流成分I 2流入該工作電壓產生電路30，而該電流成分I 1經由該分流電路90根據該分流控制信號S1所建立的該分流路徑P1流至地；同時，由於該開關元件43因未接收到任何信號而保持不導通，所以該交流電源300與該電子裝置200之間因該磁感應開關426的不導通而保持斷路。 More specifically, as shown in FIG. 3, the control unit 50 continuously outputs the shunt control signal S1 to the control terminal 91 of the shunt circuit 90 during operation of the power down mode. In this case, the constant current I (flowing from the buck rectifier circuit) will be divided into three current components I drive , I 1 , I 2 , wherein the current component I drive is turned on via the collapse. diode 22 flows to ground, the current component I 2 to flow into the working voltage generating circuit 30, and the current component I 1 via the shunt path of the shunt circuit 90 constructed in accordance with the diversion control signal S1 P1 flows to ground; while Since the switching element 43 remains non-conductive because it does not receive any signal, the AC power supply 300 and the electronic device 200 are kept open due to the non-conduction of the magnetic induction switch 426.
另一方面，如圖4所示，當該控制單元50切換至該供電模式時，該控制單元50於一預定時間期間輸出該供電控制信號S2至該開關電路40的該控制端41。在此情況下，若將該分流電路90的阻抗及該開關電路40的阻抗設計成彼此匹配時，相似於該斷電模式的情況，該電流成分I drive經由因崩潰而導通的該稽納二極體22流至地，並且該電流成分I 2流入該工作電壓產生電路30，但由於該分流電路90未建立如圖3的該分流路徑P1，所以該電流成分I 1經由該感應線圈425及導通的該開關元件43所共同建立的該導通路徑P2流至地，同時該磁感應開關426受感應磁場而導通，以致該交流電壓於該預定時間期間從該交流電源300被供應至該電子裝置200。 On the other hand, as shown in FIG. 4, when the control unit 50 switches to the power supply mode, the control unit 50 outputs the power supply control signal S2 to the control terminal 41 of the switch circuit 40 for a predetermined period of time. In this case, if the impedance of the shunt circuit 90 and the impedance of the switch circuit 40 are designed to match each other, similar to the case of the power-off mode, the current component I drive is turned on via the collapse. flows to the ground electrode 22, and the current component I 2 to flow into the working voltage generating circuit 30, but the dividing circuit 90 is not established as shown in the shunt path P1 3, so that the current component I 1 via the induction coil 425 and The conduction path P2 established by the turned-on switching element 43 flows to the ground, and the magnetic induction switch 426 is turned on by the induced magnetic field, so that the alternating voltage is supplied from the alternating current power source 300 to the electronic device 200 during the predetermined time period. .
該輸入單元70電連接該控制單元50，且能經由人為輸入而產生一時間設定輸入信號，並將該時間設定輸入信號輸出至該控制單元50。於是，該控制單元50根據該時間設定輸入信號決定該預定時間期間的長度。The input unit 70 is electrically connected to the control unit 50, and can generate a time setting input signal via a human input, and output the time setting input signal to the control unit 50. Thus, the control unit 50 determines the length of the predetermined time period based on the time setting input signal.
該指示單元80電連接且受控於該控制單元50。當該控制單元50操作在該供電模式時，該控制單元50使該指示單元80產生一用於指示該電子裝置200處於供電狀態的指示輸出。舉例來說，該指示單元80包含一指示燈(圖未示)，但不以此例為限，且在該控制單元50操作在該供電模式期間，該指示燈受控於該控制單元50以發光方式作為該指示輸出。The indicating unit 80 is electrically connected and controlled by the control unit 50. When the control unit 50 is operating in the power supply mode, the control unit 50 causes the indication unit 80 to generate an indication output for indicating that the electronic device 200 is in a power supply state. For example, the indicator unit 80 includes an indicator light (not shown), but is not limited thereto, and the indicator light is controlled by the control unit 50 during operation of the control unit 50 during the power supply mode. The illumination mode is output as the indication.
綜上所述，即使該控制單元50長時間操作在該斷電模式(即，該感應式供電控制裝置100長時間處於待命狀態)，透過該分流電路90所提供的該分流路徑P1，能使部分電流(即，該電流成分I 1)經由該分流路徑P1流至地，相較於上述現有的感應式供電控制裝置1(圖1)，確實能相對地減少經由該驅動電壓產生電路20(即，該稽納二極體22)流至地的電流大小，進而緩和該驅動電壓產生電路20的升溫現象並延緩該驅動電壓產生電路20的劣化以延長其壽命。故確實能達成本新型的目的。 In summary, even if the control unit 50 is operated in the power-off mode for a long time (that is, the inductive power supply control device 100 is in a standby state for a long time), the shunt path P1 provided by the shunt circuit 90 can A part of the current (i.e., the current component I 1 ) flows to the ground via the shunt path P1, and the relative inductive power supply control device 1 (Fig. 1) can be relatively reduced through the driving voltage generating circuit 20 ( That is, the magnitude of the current flowing to the ground by the semiconductor diode 22) further alleviates the temperature rise phenomenon of the driving voltage generating circuit 20 and delays the deterioration of the driving voltage generating circuit 20 to prolong its life. Therefore, the purpose of this novel can be achieved.
