Description
本發明係有關於一種控制裝置，尤指一種具有達到簡單之交流全電壓輸入的設計，進而更可達到節省成本的可偵測並限制電源之控制裝置。
The present invention relates to a control device, and more particularly to a control device having a design that achieves a simple AC full voltage input, thereby achieving a cost-effective detection and limiting of power.
按，目前世界各國的市電規格並未統一，而一般市電可分為有100伏特(V)、110伏特(V)、120伏特(V)、200伏特(V)、220伏特(V)、240伏特(V)，甚至工業用電有到264伏特(V)、277伏特(V)、380伏特(V)…等，所以在電器用品上常有全電壓輸入及單電壓輸入，其中前述全電壓輸入如從交流電源(AC)85伏特至交流電源(AC)264伏特，而單電壓輸入如交流電源(AC)110伏特或交流電源(AC)220伏特。
然，不管是市電或工業用電透過傳輸線(如電線)傳輸交流電源的過程中，多多少少都會損耗在傳輸線上，以導致交流電源之電壓變動；還有另一情況，就是在尖峰時間用電時同樣也會造成交流電源之電壓不穩，所以市電通常有正負百分之十的變動率，而工業用電則有正負百分之三十的變動率，因此，使得電器用品的電路無法達到所謂〝全電壓〞的操作。
另者，對於同樣瓦數的負載(如充電器、LED單元)都會有不同輸入電壓對應不同輸入電流，所以使負載及其內電路的電子元件，須設計接收不同的輸入電壓範圍(即如110V～220V)，例如若針對交流電源220伏特的輸入電壓對應之輸入電流為1安培(A)，而耗電功率為220V×1A=220瓦特(W)；若同一負載交流電源110伏特的輸入電壓對應之輸入電流為2安培(A)，而耗電功率為110V×2A=220瓦特(W)，故俾使負載及其內電路的電子元件必須採用最大耐電壓與最大耐電流的設計，亦即以220W的耗電需採用220V×2A=440W的電子元件，相對的必定會造成資源浪費，進而更重要的就是成本增加之問題。
According to the current market specifications of the world, there is no uniformity, and the general utility can be divided into 100 volts (V), 110 volts (V), 120 volts (V), 200 volts (V), 220 volts (V), 240. Volt (V), even industrial power has 264 volts (V), 277 volts (V), 380 volts (V), etc., so there are often full voltage input and single voltage input in electrical appliances, the aforementioned full voltage Inputs range from 85 volts from AC (AC) to 264 volts on AC (AC), while single-voltage inputs such as AC power (AC) 110 volts or AC power (AC) 220 volts.
However, in the process of transmitting AC power through a transmission line (such as a wire), electricity or industrial power is more or less lost on the transmission line, causing the voltage of the AC power to fluctuate. In another case, it is used during peak hours. Electricity also causes the voltage of the AC power source to be unstable. Therefore, the utility power usually has a rate of change of plus or minus 10%, while the industrial power has a rate of change of plus or minus 30%. Therefore, the circuit of the electrical appliance cannot be made. The operation of the so-called full voltage 〞 is achieved.
In addition, for the same wattage load (such as charger, LED unit), there will be different input voltages corresponding to different input currents, so the electronic components of the load and its internal circuits must be designed to receive different input voltage ranges (ie 110V). ~220V), for example, if the input voltage for the AC power supply 220 volts corresponds to an input current of 1 ampere (A), and the power consumption is 220V × 1A = 220 watts (W); if the same load AC power supply 110 volts input voltage The corresponding input current is 2 amps (A), and the power consumption is 110V × 2A = 220 watts (W), so the electronic components of the load and its internal circuits must be designed with maximum withstand voltage and maximum withstand current. That is to say, the 220W power consumption needs to use 220V × 2A = 440W electronic components, which will inevitably result in waste of resources, and more importantly, the problem of cost increase.
爰此，為有效解決上述之問題，本發明之主要目的，係提供一種具有達到簡單之交流全電壓輸入設計，以及節省成本的可偵測並限制電源之控制裝置。

並前述限制偵測單元係根據內部的一預設電壓值與時變電壓源比對，若該時變電壓源大於該預設電壓值，則關閉該控制電路；若該時變電壓源小於該預設電壓值，則開啟該控制電路，以藉由啟閉該控制電路，令所述控制電路限制於該預設電壓值內工作，以有效達到簡單之交流全電壓輸入的設計，進而更可達到節省成本的效果者。

The control device 1 includes a time-varying voltage source 2 and a control circuit 10. And a limit detecting unit 12, wherein the time-varying voltage source 2 is a power source, and the power source is a power source whose voltage changes with time, and may be selected as an AC power source or a rectified AC power source.
In addition, the control circuit 10 is connected to the time-varying voltage source 2 for controlling whether the power source passes or the current passes through the size, that is, if the control circuit 10 is controlled to be turned off and not working, thereby controlling the power source (ie, the aforementioned time-varying When the voltage source 2) fails, the relative control current is also reduced (the current is almost zero); if the control circuit 10 is controlled to be turned on, and then the control power is passed, the relative control current is also increased.
Furthermore, one end of the limit detection unit 12 is connected to the control circuit 10 at the junction of the voltage source 2, and the other end is connected to the time-varying voltage source 2, and the limit detection unit 12 is based on the internal one. The preset voltage value is compared with the time-varying voltage source 2, and if the time-varying voltage source 2 is greater than the preset voltage value, the control circuit 10 is turned off; if the time-varying voltage source 2 is smaller than the preset voltage value, The control circuit 10 is turned on, so that the time-varying voltage source 2 is detected by the limit detection unit 12, thereby controlling the opening and closing (turning on or off) the control circuit 10, and limiting the control circuit 10 to the preset voltage value. Only work, making it easy to achieve a simple AC full voltage input design.
The preset voltage value range can be selected according to the user's needs, and the control circuit 10 matches the limit detection unit 12.
Referring to FIG. 2, the control device 1 of the preferred embodiment is applied to a load 3, wherein the load 3 is selected as one of an LED unit, an LED device, a charger, and an adapter. The first and second ends 121 and 122 are respectively connected to the time-varying voltage source 2, and the control circuit 10 is provided with a third end 101 and a fourth end 102 is connected between the time-varying voltage source 2 and the first end 121, that is, the third end 101 is connected with the time-varying voltage source 2 and the first end 121. The four ends 102 are connected to one end of the load 3, and the other end of the load 3 is connected to the second end 122 and the voltage source 2 in time.
Therefore, when the limit detecting unit 12 detects that the time varying voltage source 2 is greater than the preset voltage value, the limit detecting unit 12 turns off the control circuit 10 and does not work, so that the control circuit 10 controls the power supply to fail, and the opposite The control current passes through the smaller (that is, allows the control circuit 10 to output a small current), so that the current on the load 3 also becomes smaller (ie, the current is almost zero);
If the limit detection unit 12 detects that the time-varying voltage source 2 is less than the preset voltage value, the limit detection unit 12 turns on the control circuit 10 to operate, so that the control circuit 10 controls the power supply to pass, and the opposite The control current passes through the larger (that is, the control circuit 10 is allowed to output a large current), so that the current on the load 3 also increases to the operating current of the load 3. Therefore, the control circuit 10 is turned on and off. 10 limits the operation within the preset voltage value to effectively achieve a simple AC full voltage input design, thereby further protecting the load 3 and saving cost.
3 is a block diagram showing a second preferred embodiment of the present invention; the present invention is a control device capable of detecting and limiting a power supply, comprising a time-varying voltage source 2, a control circuit 10, and a The limit detecting voltage source 2 is a power source, and the power source is a power source whose voltage changes with time, and may be selected as an AC power source or a rectified AC power source.
The other end of the control circuit 10 is connected to the time-varying voltage source 2 for controlling whether the power source passes or the current passes through the size, that is, if the control circuit 10 is controlled to be turned off and not working, then the power source is controlled (ie, the foregoing time) The variable voltage source 2) does not pass, and the relative control current is also reduced (the current is almost zero); if the control circuit 10 is controlled to be turned on, and then the control power is passed, the relative control current is also increased.
Furthermore, one end of the limit detection unit 12 is connected between the control circuit 10 and the voltage source 2, and the other end is connected to the other end of the control circuit 10, and the limit detection unit 12 is based on an internal preset. The voltage value is compared with the voltage on the control circuit 10, and if the voltage on the control circuit 10 is greater than the preset voltage value, the control circuit 10 is turned off; if the voltage on the control circuit 10 is less than the preset voltage The value of the control circuit 10 is turned on, so that the voltage of the control circuit 10 is detected by the limit detection unit 12, thereby controlling the opening and closing (turning on or off) the control circuit 10, so that the control circuit 10 is limited to the preset. Only work within the voltage value, making it possible to achieve a simple AC full voltage input design.
The preset voltage value range can be selected according to the user's needs, and the control circuit 10 matches the limit detection unit 12.
Referring to FIG. 4, the control device 1 of the preferred embodiment is applied to a load 3, wherein the load 3 is selected as one of an LED unit, an LED device, a charger, and an adapter. The first detection terminal 10 is provided with a first end 121 and a second end 122. The control circuit 10 is provided with a third end 101 and a fourth end 102. The third end 101 is in time with the first end 121. The variable voltage source 2 is connected in common. The fourth end 102 is connected to the second end 122 and one end of the load 3. The other end of the load 3 is connected to the time-varying voltage source 2.
Therefore, when the limit detecting unit 12 detects that the voltage on the control circuit 10 is greater than the preset voltage value, the limit detecting unit 12 turns off the control circuit 10, and the control circuit 10 controls the power supply to fail. The control current is made smaller (that is, the control circuit 10 is allowed to output a small current), so that the current on the load 3 is also reduced (that is, the current is almost zero);
If the limit detection unit 12 detects that the voltage on the control circuit 10 is less than the preset voltage value, the limit detection unit 12 turns on the control circuit 10 to operate, so that the control circuit 10 controls the power supply to pass. The control current is increased (that is, the control circuit 10 is allowed to output a large current), so that the current on the load 3 is also increased to the operating current of the load 3. Therefore, the control circuit 10 is turned on and off. The circuit 10 is limited to operate within the preset voltage value to effectively achieve a simple AC full voltage input design, thereby further protecting the load 3 and saving cost.
