Description
本發明係與電源供應器有關；特別是指一種具有兩個電源的電源供應器及其電池進行充電和放電之方法。The present invention relates to a power supply; in particular, to a power supply having two power supplies and a method of charging and discharging the same.
近年來隨著科技的進步，具有各式各樣不同功能的電子產品已逐漸被研發出來，這些具有各式各樣不同功能的電子產品不但滿足了人們的各種不同需求，更融入每個人的日常生活，使得人們生活更為便利。In recent years, with the advancement of technology, electronic products with various functions have been gradually developed. These electronic products with various functions not only meet the various needs of people, but also integrate into everyone's daily life. Life makes people's lives more convenient.
這些各式各樣不同功能的電子產品係由各種電子元件所組成，而每一個電子元件所需的電源電壓不盡相同，因此，為了提供適當的電壓給每一個電子元件使其正常運作，因此需要一電源供應器，將電池或是市電所提供的電能，轉換成具有特定電壓或是電流，使這些電子產品能維持運作。These various electronic products of different functions are composed of various electronic components, and each of the electronic components requires different power supply voltages. Therefore, in order to provide an appropriate voltage for each electronic component to operate normally, A power supply is needed to convert the power provided by the battery or mains into a specific voltage or current to keep these electronic products operational.
電源供應器依其電路架構的不同，約可粗略地區分為線性式和交換式電源轉換電路兩種，簡單的線性式電源轉換電路是由變壓器、二極體整流器和電容濾波器所組成，其優點是電路簡單且成本低，但是因使用較大的變壓器且轉換效率低，所以無法使用在體積較小或長時間使用的電子產品中。相較於線性式電源轉換電路，交換式電源轉換電路具有較高的轉換效率及較小的體積，因此，長時間使用的電子產品大多會使用交換式電源轉換電路。According to the different circuit architectures, the power supply can be roughly divided into two types: linear and switched power conversion circuits. The simple linear power conversion circuit is composed of a transformer, a diode rectifier and a capacitor filter. The advantage is that the circuit is simple and low in cost, but because of the use of a large transformer and low conversion efficiency, it cannot be used in electronic products that are small in size or used for a long time. Compared with linear power conversion circuits, switching power conversion circuits have higher conversion efficiency and smaller size. Therefore, most of the electronic products used for a long time use switching power conversion circuits.
但一般使用交換式電源轉換電路的電源供應器都藉由外接市電或是內接電池來獲得電能，因此當臨時停電或者電池突然的損壞，使負載因斷電而停止作動，讓使用者完全無反應時間可進行處理，而造成難以估計損失。However, the power supply that generally uses the switching power conversion circuit obtains power by external power supply or internal battery. Therefore, when the power is temporarily cut off or the battery is suddenly damaged, the load is stopped due to power failure, leaving the user completely free. The reaction time can be processed, making it difficult to estimate the loss.

Hereinafter, the operation of the signal and related elements outputted by the control circuit 130 when the battery BT is charged and discharged will be described.
電池BT放電動作：Battery BT discharge action:
如圖３及圖４所示，於第一時間T1時，該控制電路130之第一輸出端S1、第二輸出端S2及第四輸出端S4輸出高電位，第三輸出端S3輸出低電位，使該第一開關Q1、該第二開關Q2及該第四開關Q4導通，第三開關Q3截止。該電池BT透過該第一開關Q1及該第二開關Q2而與該電感L之兩端電性連接，且電池BT之第一電壓值V1大於該直流電壓源DC的第二電壓，因此，在第二二極體D2為逆向遍壓的情況下，該直流電壓源DC不提供任何電壓或電流，而造成該直流電壓DC與該電感L之間呈現斷路，使該電感L上的壓降VL為該電池BT之第一電壓值V1，即為該電感L具有該第一電壓值V1。同時，該電池BT對電感L釋放能量，使電感L進行儲能，進而使流經該電感L之電流IL上升至一第一電流值I1。此外，在第一時間T1時，該第一電容C1之電壓值大於該第四二極體D4之正端處的電壓值，使該第四二極體D4呈現逆向偏壓，而造成該第四開關Q4與該第一電容C1及第二電容C2呈現斷路，因此該第一電容C1只對該第一負載R1釋放能量、該第二電容C2對該第二負載R2釋放能量以及該第三電容C3對該第三負載R3釋放能量，使該些負載能維持在作動的狀態。As shown in FIG. 3 and FIG. 4, at the first time T1, the first output terminal S1, the second output terminal S2, and the fourth output terminal S4 of the control circuit 130 output a high potential, and the third output terminal S3 outputs a low potential. The first switch Q1, the second switch Q2, and the fourth switch Q4 are turned on, and the third switch Q3 is turned off. The battery BT is electrically connected to both ends of the inductor L through the first switch Q1 and the second switch Q2, and the first voltage value V1 of the battery BT is greater than the second voltage of the DC voltage source DC, and therefore, When the second diode D2 is reversed, the DC voltage source DC does not provide any voltage or current, and the DC voltage DC and the inductor L are disconnected, so that the voltage drop VL on the inductor L It is the first voltage value V1 of the battery BT, that is, the inductance L has the first voltage value V1. At the same time, the battery BT releases energy to the inductor L, so that the inductor L stores energy, and the current IL flowing through the inductor L rises to a first current value I1. In addition, at the first time T1, the voltage value of the first capacitor C1 is greater than the voltage value at the positive terminal of the fourth diode D4, so that the fourth diode D4 is reverse biased, thereby causing the first The fourth switch Q4 and the first capacitor C1 and the second capacitor C2 are open circuited, so the first capacitor C1 only releases energy to the first load R1, the second capacitor C2 releases energy to the second load R2, and the third Capacitor C3 releases energy to the third load R3 to maintain the loads in an active state.
如圖３及圖５所示，於第二時間T2時，該控制電路130之第二輸出端S2及第四輸出端S4輸出高電位，該第一輸出端S1及該第三輸出端S3輸出低電位，使該第二開關Q2及該第四開關Q4導通，該第一開關Q1及第三開關Q3截止。該直流電壓源DC透過該第二二極體D2及該第二開關Q2而與該電感L之兩端電性連接，使該電感L上的壓降VL為該直流電壓源DC之第二電壓值V2，即該電感L具有該第二電壓值V2，同時，該直流電壓源DC對電感L釋放能量，讓電感L進行儲能，使流經該電感L之電流由該第一電流值I1上升至一第二電流值I2。此外，該第一電容C1之電壓值大於該第四二極體D4之正端處的電壓值，使該第四二極體D4呈現逆向偏壓，而造成該第四開關Q4與該第一電容C1及第二電容C2之間呈現斷路，因此在第二時間T2時，該第一電容C1只對該第一負載R1釋放能量、該第二電容C2對該第二負載R2釋放能量以及該第三電容C3對該第三負載R3釋放能量，使該些負載能維持在作動的狀態。As shown in FIG. 3 and FIG. 5, at the second time T2, the second output terminal S2 and the fourth output terminal S4 of the control circuit 130 output a high potential, and the first output terminal S1 and the third output terminal S3 output. The second switch Q2 and the fourth switch Q4 are turned on by the low potential, and the first switch Q1 and the third switch Q3 are turned off. The DC voltage source DC is electrically connected to both ends of the inductor L through the second diode D2 and the second switch Q2, so that the voltage drop VL on the inductor L is the second voltage of the DC voltage source DC. The value V2, that is, the inductance L has the second voltage value V2. At the same time, the DC voltage source DC releases energy to the inductor L, so that the inductor L stores energy, so that the current flowing through the inductor L is from the first current value I1. It rises to a second current value I2. In addition, the voltage value of the first capacitor C1 is greater than the voltage value at the positive terminal of the fourth diode D4, so that the fourth diode D4 exhibits a reverse bias, thereby causing the fourth switch Q4 and the first An open circuit is formed between the capacitor C1 and the second capacitor C2. Therefore, at the second time T2, the first capacitor C1 releases energy only to the first load R1, the second capacitor C2 releases energy to the second load R2, and the The third capacitor C3 releases energy to the third load R3 to maintain the loads in an active state.
如圖３及圖６所示，於第三時間T3時，該控制電路130之第四輸出端S4輸出高電位，該第一輸出端S1、該第二輸出端S2及該第三輸出端S3輸出低電位，使該第四開關Q4導通，該第一開關Q1、該第二開關Q2及第三開關Q3截止。因為該第二開關Q2截止，且該第四開關Q4導通，使流經該電感L透過第四開關Q4而與該第一電容C1電性連接，使該電感L的壓降VL為該第二電壓值V2減第一電容C1上的電壓值，而得到一第三電壓值V3(即為由第二電壓值V2降為第三電壓值V3)，而電感L開始對該第一電容C1以及該第一負載R1釋放能量，使該第一負載R1維持在作動的狀態。該第一電容C1藉由電感L的釋放能量而進行儲存能量，而流經該電感L之電流由該第二電流值I2下降至一第三電流值I3。此外，在第三時間T3時該第二電容C2對該第二負載R2釋放能量以及該第三電容C3對該第三負載R3釋放能量，使該些負載能維持在作動的狀態。As shown in FIG. 3 and FIG. 6, at the third time T3, the fourth output terminal S4 of the control circuit 130 outputs a high potential, the first output terminal S1, the second output terminal S2, and the third output terminal S3. The output of the low potential causes the fourth switch Q4 to be turned on, and the first switch Q1, the second switch Q2, and the third switch Q3 are turned off. Because the second switch Q2 is turned off, and the fourth switch Q4 is turned on, the inductor L is electrically connected to the first capacitor C1 through the fourth switch Q4, so that the voltage drop VL of the inductor L is the second The voltage value V2 is reduced by the voltage value of the first capacitor C1, and a third voltage value V3 is obtained (that is, the second voltage value V2 is decreased to the third voltage value V3), and the inductor L starts to the first capacitor C1 and The first load R1 releases energy to maintain the first load R1 in an actuated state. The first capacitor C1 stores energy by the release energy of the inductor L, and the current flowing through the inductor L decreases from the second current value I2 to a third current value I3. In addition, at the third time T3, the second capacitor C2 releases energy to the second load R2 and the third capacitor C3 releases energy to the third load R3, so that the loads can be maintained in an active state.
如圖３及圖７所示，於第四時間T4時，該控制電路130之該第一輸出端S1、該第二輸出端S2、該第三輸出端S3及第四輸出端S4輸出低電位，使該第一開關Q1、該第二開關Q2及第三開關Q3及第四開關Q4截止。此時，該第一二極體D1為順向偏壓而導通，使該電感L之電壓為第二電壓減去第一電容C1及第二電容C2上的壓降VL，而得到一第四電壓值V4(即為由第三電壓值V3降為第四電壓值V4)。該電感L持續釋放能量，且釋放的能量一部份流入該變壓電路110的輸入側，使該變壓電路110之輸出側中第五二極體D5正端的電壓值大於該第三電容C3上的電壓值，而對該第三電容C3及該第三負載R3釋放能量。該電感L所釋放的另一部份能量經由該第一二極體D1而傳送至該第一電容C1、該第二電容C2、該第一電阻及該第二電阻。該電感L經過釋放能量後，該電感L之電流由該第三電流值I3下降至一第四電流值I4。此外，該第一電容C1、該第二電容C2以及該第三電容C3藉由電感L的釋放能量而進行儲存能量。As shown in FIG. 3 and FIG. 7, at the fourth time T4, the first output terminal S1, the second output terminal S2, the third output terminal S3, and the fourth output terminal S4 of the control circuit 130 output a low potential. The first switch Q1, the second switch Q2, the third switch Q3, and the fourth switch Q4 are turned off. At this time, the first diode D1 is turned on by the forward bias, and the voltage of the inductor L is the second voltage minus the voltage drop VL on the first capacitor C1 and the second capacitor C2, and a fourth is obtained. The voltage value V4 (ie, is reduced from the third voltage value V3 to the fourth voltage value V4). The inductor L continuously releases energy, and a part of the released energy flows into the input side of the transformer circuit 110, so that the voltage value of the positive terminal of the fifth diode D5 in the output side of the transformer circuit 110 is greater than the third capacitor C3. The upper voltage value releases energy to the third capacitor C3 and the third load R3. Another portion of the energy released by the inductor L is transmitted to the first capacitor C1, the second capacitor C2, the first resistor, and the second resistor via the first diode D1. After the inductor L is released, the current of the inductor L is decreased from the third current value I3 to a fourth current value I4. In addition, the first capacitor C1, the second capacitor C2, and the third capacitor C3 store energy by the energy released by the inductor L.
本實施例的電源供應器之電池BT放電的動作，以第一時間T1至第四時間T4為一個循環，且藉由第一時間T1中，電池BT對電感L儲能，使電感L的電流增加，然後再第二時間T2中，直流電壓源DC再對電感L儲能，使電感L的電流再增加，且在第一時間T1及第二時間T2時，該電容組120持續對負載組910釋放能量，而使負載組910作動。之後在第三時間T3及第四時間T4，電感L開始釋放能量，而對電容組120及負載組910進行放電，使電容組120能夠進行儲能以及使負載組910能夠作動。The operation of the battery BT discharge of the power supply of the embodiment is a cycle from the first time T1 to the fourth time T4, and by the first time T1, the battery BT stores the energy of the inductor L, so that the current of the inductor L Then, in the second time T2, the DC voltage source DC stores energy to the inductor L again, so that the current of the inductor L increases again, and at the first time T1 and the second time T2, the capacitor group 120 continues to the load group. 910 releases energy and causes load group 910 to actuate. Then, at the third time T3 and the fourth time T4, the inductor L starts to release energy, and discharges the capacitor group 120 and the load group 910 to enable the capacitor group 120 to perform energy storage and enable the load group 910 to operate.
電池BT充電動作：Battery BT charging action:
電池BT充電動作與電池BT放電動作同樣由四段時間組成，但為了避免與電池BT放電動作中的第一時間至第四時間產生混肴，將以第五時間T5至第八時間T8來說明電池BT充電動作中，四段不同時間之動作。The battery BT charging action and the battery BT discharging action are also composed of four periods of time, but in order to avoid mixing with the first time to the fourth time in the battery BT discharging operation, the fifth time T5 to the eighth time T8 will be explained. In the battery BT charging action, four different time actions.
如圖５及圖８所示，於第五時間T5時，該控制電路130之第二輸出端S2、該第三輸出端S3及第該四輸出端S4輸出高電位，該第一輸出端S1輸出低電位，使該第二開關Q2、該第三開關Q3及該第四開關Q4導通，該第一開關Q1截止。該直流電壓源DC透過該第二二極體D2及該第二開關Q2而與該電感L之兩端電性連接，且該電池BT之電壓值大於該第三二極體D3之正端處的電壓值，使該第三二極體D3呈現逆向偏壓，而造成該第三開關Q3與該電感L之間呈現斷路，因此該電感L上的電壓值為該直流電壓源DC之第二電壓值V2，即該電感L具有該第二電壓值V2，但為了與上述電池BT放電動作中的第二時間T2的第二電值進行區別，將第五時間T5的電感L上的壓降VL定為第五電壓值V5。此外，該直流電壓源DC對電感L釋放能量，讓電感L進行儲能，使流經該電感L之電流上升至一第五電流值I5。此外，在第五時間T5時，該第一電容C1之電壓值大於該第四二極體D4之正端處的電壓值，使該第四二極體D4呈現逆向偏壓，而造成該第四開關Q4與該第一電容C1及第二電容C2之間呈現斷路，因此該第一電容C1只對該第一負載R1釋放能量、該第二電容C2對該第二負載R2釋放能量以及該第三電容C3對該第三負載R3釋放能量，使該些負載能維持在作動的狀態。As shown in FIG. 5 and FIG. 8 , at the fifth time T5, the second output terminal S2, the third output terminal S3 and the fourth output terminal S4 of the control circuit 130 output a high potential, and the first output terminal S1 The output of the low potential causes the second switch Q2, the third switch Q3, and the fourth switch Q4 to be turned on, and the first switch Q1 is turned off. The DC voltage source DC is electrically connected to both ends of the inductor L through the second diode D2 and the second switch Q2, and the voltage value of the battery BT is greater than the positive end of the third diode D3. The voltage value causes the third diode D3 to be reverse biased, causing an open circuit between the third switch Q3 and the inductor L. Therefore, the voltage value on the inductor L is the second of the DC voltage source DC. The voltage value V2, that is, the inductance L has the second voltage value V2, but in order to distinguish from the second electric value of the second time T2 in the discharge operation of the battery BT, the voltage drop across the inductance L of the fifth time T5 VL is set to the fifth voltage value V5. In addition, the DC voltage source DC releases energy to the inductor L, and the inductor L stores energy, so that the current flowing through the inductor L rises to a fifth current value I5. In addition, at the fifth time T5, the voltage value of the first capacitor C1 is greater than the voltage value at the positive terminal of the fourth diode D4, so that the fourth diode D4 is reverse biased, thereby causing the first The fourth switch Q4 and the first capacitor C1 and the second capacitor C2 are disconnected, so the first capacitor C1 only releases energy to the first load R1, the second capacitor C2 releases energy to the second load R2, and the The third capacitor C3 releases energy to the third load R3 to maintain the loads in an active state.
如圖８及圖９所示，於第六時間T6時，該控制電路130之第三輸出端S3及第四輸出端S4輸出高電位，該第一輸出端S1及該第二輸出端S2輸出低電位，使該第三開關Q3及該第四開關Q4導通，該第一開關Q1及第二開關Q2截止。該直流電壓源DC以及電池BT透過該第二二極體D2、第三二極體D3及該第三開關Q3而與該電感L電性連接，使該電感L上的壓降VL為第二電壓值V2減第一電壓值V1，而得到一第六電壓值V6(即為由第五電壓值V5降為第六電壓值V6)。As shown in FIG. 8 and FIG. 9, at the sixth time T6, the third output terminal S3 and the fourth output terminal S4 of the control circuit 130 output a high potential, and the first output terminal S1 and the second output terminal S2 output. At a low potential, the third switch Q3 and the fourth switch Q4 are turned on, and the first switch Q1 and the second switch Q2 are turned off. The DC voltage source DC and the battery BT are electrically connected to the inductor L through the second diode D2, the third diode D3 and the third switch Q3, so that the voltage drop VL on the inductor L is the second The voltage value V2 is decreased by the first voltage value V1 to obtain a sixth voltage value V6 (that is, reduced from the fifth voltage value V5 to the sixth voltage value V6).
在第六時間T6中，由於電感L的特性，使流過電感L之電流IL方向不變，因此對該電池BT釋放能量，使流經電感L的電流會由第五電流值I5減少至第六電流值I6。此外，在第六時間T6時，該第一電容C1之電壓值大於該第四二極體D4之正端處的電壓值，使該第四二極體D4呈現逆向偏壓，而造成該第四開關Q4與該第一電容C1及第二電容C2之間呈現斷路，因此該第一電容C1只對該第一負載R1釋放能量、該第二電容C2對該第二負載R2釋放能量以及該第三電容C3對該第三負載R3釋放能量，使該些負載能維持在作動的狀態。In the sixth time T6, due to the characteristic of the inductance L, the direction of the current IL flowing through the inductor L is unchanged, so that the energy is released to the battery BT, so that the current flowing through the inductor L is reduced from the fifth current value I5 to the first Six current values I6. In addition, at the sixth time T6, the voltage value of the first capacitor C1 is greater than the voltage value at the positive terminal of the fourth diode D4, so that the fourth diode D4 is reverse biased, thereby causing the first The fourth switch Q4 and the first capacitor C1 and the second capacitor C2 are disconnected, so the first capacitor C1 only releases energy to the first load R1, the second capacitor C2 releases energy to the second load R2, and the The third capacitor C3 releases energy to the third load R3 to maintain the loads in an active state.
如圖６及圖８所示，於第七時間T7時，該控制電路130之第四輸出端S4輸出高電位，以及該第一輸出端S1、該第二輸出端S2及第三輸出端S3輸出低電位，使該第四開關Q4導通，該第一開關Q1、第二開關Q2及該第三開關Q3截止。因為該第一開關Q1及該第三開關Q3截止，且第四開關Q4導通，使流經該電感L透過第四開關Q4而與該第一電容C1電性連接，使該電感L的壓降VL為該第一電壓值V1減第一電容C1上的電壓值，而得到一第七電壓值V7(即為由第六電壓值V6降為第七電壓值V7)，而電感L開始對該第一電容C1以及該第一負載R1釋放能量，使該第一負載R1維持在作動的狀態。該第一電容C1藉由電感L的釋放能量而進行儲存能量，使流經該電感L之電流由該第六電流值I6下降至一第七電流值I7。此外，在第七時間T7時該第二電容C2對該第二負載R2釋放能量以及該第三電容C3對該第三負載R3釋放能量，使該些負載能維持在作動的狀態。As shown in FIG. 6 and FIG. 8 , at the seventh time T7, the fourth output terminal S4 of the control circuit 130 outputs a high potential, and the first output terminal S1, the second output terminal S2, and the third output terminal S3. The output of the low potential causes the fourth switch Q4 to be turned on, and the first switch Q1, the second switch Q2, and the third switch Q3 are turned off. Because the first switch Q1 and the third switch Q3 are turned off, and the fourth switch Q4 is turned on, the inductor L is electrically connected to the first capacitor C1 through the fourth switch Q4, so that the voltage drop of the inductor L is VL is the first voltage value V1 minus the voltage value on the first capacitor C1, and a seventh voltage value V7 is obtained (that is, the sixth voltage value V6 is decreased to the seventh voltage value V7), and the inductor L starts to The first capacitor C1 and the first load R1 release energy to maintain the first load R1 in an actuated state. The first capacitor C1 stores energy by the release energy of the inductor L, so that the current flowing through the inductor L decreases from the sixth current value I6 to a seventh current value I7. In addition, at the seventh time T7, the second capacitor C2 releases energy to the second load R2 and the third capacitor C3 releases energy to the third load R3, so that the loads can be maintained in an active state.
如圖８及圖７所示，於第八時間T8時，該控制電路130之該第一輸出端S1、該第二輸出端S2、該第三輸出端S3及第四輸出端S4輸出低電位，使該第一開關Q1、該第二開關Q2及第三開關Q3及第四開關Q4截止。此時，該第一二極體D1為順向偏壓而導通，使該電感L之壓降VL為第二電壓減第一電容C1及第二電容C2上的電壓值，而得到一第八電壓值V8(即為由第七電壓值V7降為第八電壓值V8)。該電感L持續釋放能量，且釋放的能量一部份流入該變壓電路110的輸入側，使該變壓電路110之輸出側中第五二極體D5正端的電壓值大於該第三電容C3上的電壓值，而對該第三電容C3及該第三負載R3釋放能量。該電感L所釋放的另一部份能量經由該第一二極體D1而傳送至該第一電容C1、該第二電容C2、該第一電阻及該第二電阻。該電感L經過釋放能量後，該電感L之電流由該第七電流值I7下降至一第八電流值I8。此外，該第一電容C1、該第二電容C2以及該第三電容C3藉由電感L的釋放能量而進行儲存能量。As shown in FIG. 8 and FIG. 7, at the eighth time T8, the first output terminal S1, the second output terminal S2, the third output terminal S3, and the fourth output terminal S4 of the control circuit 130 output a low potential. The first switch Q1, the second switch Q2, the third switch Q3, and the fourth switch Q4 are turned off. At this time, the first diode D1 is turned on in the forward bias, so that the voltage drop VL of the inductor L is the second voltage minus the voltage value on the first capacitor C1 and the second capacitor C2, and an eighth is obtained. The voltage value V8 (that is, is reduced from the seventh voltage value V7 to the eighth voltage value V8). The inductor L continuously releases energy, and a part of the released energy flows into the input side of the transformer circuit 110, so that the voltage value of the positive terminal of the fifth diode D5 in the output side of the transformer circuit 110 is greater than the third capacitor C3. The upper voltage value releases energy to the third capacitor C3 and the third load R3. Another portion of the energy released by the inductor L is transmitted to the first capacitor C1, the second capacitor C2, the first resistor, and the second resistor via the first diode D1. After the inductor L is released, the current of the inductor L is decreased from the seventh current value I7 to an eighth current value I8. In addition, the first capacitor C1, the second capacitor C2, and the third capacitor C3 store energy by the energy released by the inductor L.
本實施例的電源供應器100之電池BT充電的動作，以第五時間T5至第八時間T8為一個循環，然後於第五時間T5中，該直流電壓源DC對該電感L儲能，使電感L的電流增加，然後在第六時間T6中，該電感L對該電池BT釋放能量，使電池BT進行充電，且在第五時間T5及第六時間T6時，該電容組120持續對負載組910釋放能量，而使負載組910作動。之後在第七時間T7及第八時間T8時，電感L開始釋放能量，而對電容組120及負載組910進行放電，使電容組120能夠進行儲能以及使負載組910能夠作動，The charging operation of the battery BT of the power supply 100 of the embodiment is performed in a cycle from the fifth time T5 to the eighth time T8, and then in the fifth time T5, the DC voltage source DC stores the inductance L, so that The current of the inductor L increases, and then in the sixth time T6, the inductor L releases energy to the battery BT to charge the battery BT, and at the fifth time T5 and the sixth time T6, the capacitor group 120 continues to load Group 910 releases energy while causing load group 910 to act. Then, at the seventh time T7 and the eighth time T8, the inductor L starts to release energy, and discharges the capacitor group 120 and the load group 910 to enable the capacitor group 120 to perform energy storage and enable the load group 910 to operate.
在本實施例中，在設計電源供應器100時，可依據所使用元件或負載之特性，而進行不同次數及順序的電池BT放電動作及電池BT充電動作，例如，以交錯執行電池BT放電動作與電池BT充電動作的方式進行動作，或者先執行數次的電池BT放電動作，之後再執行一次電池BT充電動作。In the present embodiment, when the power supply 100 is designed, different times and sequences of battery BT discharge operations and battery BT charging operations may be performed depending on the characteristics of the components or loads used, for example, to alternately perform battery BT discharge operations. The battery BT charging operation is performed, or the battery BT discharging operation is performed several times, and then the battery BT charging operation is performed once.
綜上所述，本發明電源供應器具有直流電壓源及電池等兩個電源，且利用第一開關至第四開關的開啟以關閉，以對電池進行充電及放電，同時還對負載組進行釋放能量，以保持負載作動，此外，若是有其中一電源損壞時，還有另一電源可持續對負載組進行供電，以避免臨時的斷電，而造成使用者的損失。In summary, the power supply of the present invention has two power sources, such as a DC voltage source and a battery, and is turned off by using the first to fourth switches to charge and discharge the battery, and simultaneously release the load group. The energy is used to keep the load active. In addition, if one of the power supplies is damaged, another power source can continue to supply power to the load group to avoid temporary power failure, causing loss to the user.
以上所述僅為本發明較佳可行實施例而已，舉凡應用本發明說明書及申請專利範圍所為之等效變化，理應包含在本發明之專利範圍內。The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
