Description
本發明係有關於一種放電電路及電源供應裝置，特別是一種快速放電電路及具有快速放電電路之電源供應裝置。 The present invention relates to a discharge circuit and a power supply device, and more particularly to a fast discharge circuit and a power supply device having a fast discharge circuit.
電源供應器是一種常見的電子裝置；電源供應器提供電源予電子裝置，藉以驅動電子裝置；因此，電源供應器非常重要。通常，電源供應器係接收交流電源並轉換交流電源成為輸出直流電源。 A power supply is a common electronic device; a power supply provides power to an electronic device to drive the electronic device; therefore, the power supply is very important. Typically, the power supply receives AC power and converts AC power to output DC power.
現在一般電源供應器具有兩種不同的輸出電壓：高電壓(例如32伏特、30伏特或24伏特等等)與低電壓(例如15伏特、12伏特或5伏特等等)；當電源供應器工作在正常狀態下(例如提供電源予電子裝置)，電源供應器的輸出電壓為高電壓；當電源供應器在休眠狀態或待機狀態下，電源供應器的輸出電壓必須轉變為低電壓以節能；因為電源供應器的輸出端具有輸出端電容，因此從高電壓改變為低電壓的切換時間會被延長，如此將造成系統偵測進入休眠狀態或待機狀態時間拉長；因此，此時電源供應器的輸出端電容必須快速地放電，使得電源供應器的輸出端電容的電位為低電位。 Now the general power supply has two different output voltages: high voltage (such as 32 volts, 30 volts or 24 volts, etc.) and low voltage (such as 15 volts, 12 volts or 5 volts, etc.); when the power supply works In a normal state (for example, providing power to an electronic device), the output voltage of the power supply is a high voltage; when the power supply is in a sleep state or a standby state, the output voltage of the power supply must be converted to a low voltage to save energy; The output of the power supply has an output capacitor, so the switching time from high voltage to low voltage is prolonged, which will cause the system to detect the sleep state or the standby state is extended; therefore, the power supply at this time The output capacitor must be discharged quickly so that the potential of the output capacitor of the power supply is low.
然而，一般電源供應器的缺點為當電源供應器的輸出電壓從高電壓變為低電壓時，電源供應器的輸出端電容不能快速地放電。 However, a general power supply has a disadvantage in that the output capacitance of the power supply cannot be quickly discharged when the output voltage of the power supply is changed from a high voltage to a low voltage.
為改善上述習知技術之缺點，本發明之目的在於提供一種快速放電電路。 In order to improve the above disadvantages of the prior art, it is an object of the present invention to provide a fast discharge circuit.

The current limiting unit 10604; the converter 207 is electrically connected to the power processing primary side circuit 206 and the power processing secondary side circuit 208.
該耗能單元102電性連接至該電源輸出端202及該輸出端電容204；該開關單元104電性連接至該耗能單元102；該開關控制單元106電性連接至該開關單元104；該充放電子單元10602電性連接至該開關單元104；該放電子單元10606電性連接至該開關單元104及該充放電子單元10602；該限流子單元10604電性連接至該充放電子單元10602；該耗能元件10608電性連接至該開關單元104及該充放電子單元10602；該電流單向 元件10610電性連接至該開關單元104、該充放電子單元10602及該耗能元件10608。 The power consuming unit 102 is electrically connected to the power output terminal 202 and the output terminal capacitor 204; the switch unit 104 is electrically connected to the energy consuming unit 102; the switch control unit 106 is electrically connected to the switch unit 104; The charging and discharging unit 10602 is electrically connected to the switching unit 104. The discharging unit 10606 is electrically connected to the switching unit 104 and the charging and discharging unit 10602. The limiting unit 10604 is electrically connected to the charging and discharging unit 10602; the energy consuming component 10608 is electrically connected to the switch unit 104 and the charging and discharging electronic unit 10602; the current is unidirectional The component 10610 is electrically connected to the switch unit 104, the charging and discharging electronic unit 10602, and the energy consuming component 10608.
當該開關控制單元106接收到一休眠信號108(例如一高信號，high signal)時，該開關控制單元106導通該開關單元104，使得該輸出端電容204對該耗能單元102放電(一放電路徑為該輸出端電容204、該耗能單元102、該開關單元104及地)。再者，該休眠信號108可來自於該電子裝置40、該電源供應器20或任何地方；該休眠信號108表示該電子裝置40或該電源供應器20將進入一休眠狀態或一待機狀態，此時該電源供應器20的一輸出電壓必須轉變為一低電壓以節能，因此該輸出端電容204必須快速地放電，使得該輸出端電容204的一電位為一低電位。 When the switch control unit 106 receives a sleep signal 108 (eg, a high signal), the switch control unit 106 turns on the switch unit 104, so that the output capacitor 204 discharges the energy consuming unit 102 (a discharge) The path is the output capacitor 204, the energy consuming unit 102, the switch unit 104, and ground). Moreover, the sleep signal 108 can be from the electronic device 40, the power supply 20 or anywhere; the sleep signal 108 indicates that the electronic device 40 or the power supply 20 will enter a sleep state or a standby state, An output voltage of the power supply 20 must be converted to a low voltage to save energy, so the output capacitor 204 must be quickly discharged such that a potential of the output capacitor 204 is a low potential.
在一具體實施例，該充放電子單元10602係為一電容，該開關單元104可為例如但不限定為一NMOS；當該充放電子單元10602被該休眠信號108充電且該充放電子單元10602未被充飽電時，該開關單元104被導通(因為電容被充電但未被充飽電的現象)，使得該輸出端電容204對該耗能單元102放電。再者，一旦該充放電子單元10602被充飽電時，該開關單元104即不被導通(因為電容被充飽電的現象；被充飽電的電容會阻隔直流電)，使得該輸出端電容204不對該耗能單元102放電。該開關單元104的導通時間可由該充放電子單元10602及該限流子單元10604控制；該充放電子單元10602的電容值越大，則該輸出端電容204的放電時間越久。 In one embodiment, the charging and discharging electronic unit 10602 is a capacitor, and the switching unit 104 can be, for example but not limited to, an NMOS; when the charging and discharging electronic unit 10602 is charged by the sleep signal 108 and the charging and discharging electronic unit When the 10602 is not fully charged, the switch unit 104 is turned on (because the capacitor is charged but not fully charged), so that the output capacitor 204 discharges the energy consuming unit 102. Moreover, once the charging and discharging electronic unit 10602 is fully charged, the switching unit 104 is not turned on (because the capacitor is fully charged; the fully charged capacitor blocks the direct current), so that the output capacitor 204 does not discharge the energy consuming unit 102. The on-time of the switching unit 104 can be controlled by the charging and discharging electronic unit 10602 and the current limiting sub-unit 10604; the larger the capacitance value of the charging and discharging electronic unit 10602, the longer the discharging time of the output terminal 204.
當該開關控制單元106接收到一非休眠信號110(例如一低信號，low signal，或一接地信號)時，該充放電子單元10602對該放電子單元10606放電，且該開關單元104不被導通，使得該輸出端電容204不對該耗能單元102放電。再者，該非休眠信號110可來自於該電子裝置40、該電源供應器20或任何地方；該非休眠信號110代表該電源供應器20將工作在一正常狀態(例如提供電源予該電子裝置40)，該電源供應器20的輸出 電壓為一高電壓。該限流子單元10604的一端連接該充放電子單元10602；在一具體實施例，該限流子單元10604的另一端接地即代表該開關控制單元106接收到該非休眠信號110。 When the switch control unit 106 receives a non-sleep signal 110 (eg, a low signal, a low signal, or a ground signal), the charging and discharging electronic unit 10602 discharges the electronic discharge unit 10606, and the switch unit 104 is not The conduction is such that the output capacitor 204 does not discharge the energy consuming unit 102. Moreover, the non-dormant signal 110 can be from the electronic device 40, the power supply 20 or anywhere; the non-sleep signal 110 represents that the power supply 20 will operate in a normal state (eg, providing power to the electronic device 40) The output of the power supply 20 The voltage is a high voltage. One end of the current limiting subunit 10604 is connected to the charging and discharging electronic unit 10602. In one embodiment, the other end of the current limiting subunit 10604 is grounded, that is, the switch control unit 106 receives the non-dormant signal 110.

在一具體實施例，該充放電子單元10602係為一電容，該開關單元104可為例如但不限定為一NMOS；當該充放電子單元10602被該休眠信號108充電且該充放電子單元10602未被充飽電時，該開關單元104被導通(因為電容被充電但未被充飽電的現象)，使得該輸出端電容204對該耗能單元102放電。 再者，一旦該充放電子單元10602被充飽電時，該開關單元104即不被導通(因為電容被充飽電的現象；被充飽電的電容會阻隔直流電)，使得該輸出端電容204不對該耗能單元102放電。該開關單元104的導通時間可由該充放電子單元10602及該限流子單元10604控制；該充放電子單元10602的電容值越大，則該輸出端電容204的放電時間越久。 In one embodiment, the charging and discharging electronic unit 10602 is a capacitor, and the switching unit 104 can be, for example but not limited to, an NMOS; when the charging and discharging electronic unit 10602 is charged by the sleep signal 108 and the charging and discharging electronic unit When the 10602 is not fully charged, the switch unit 104 is turned on (because the capacitor is charged but not fully charged), so that the output capacitor 204 discharges the energy consuming unit 102. Moreover, once the charging and discharging electronic unit 10602 is fully charged, the switching unit 104 is not turned on (because the capacitor is fully charged; the fully charged capacitor blocks the direct current), so that the output capacitor 204 does not discharge the energy consuming unit 102. The on-time of the switching unit 104 can be controlled by the charging and discharging electronic unit 10602 and the current limiting sub-unit 10604; the larger the capacitance value of the charging and discharging electronic unit 10602, the longer the discharging time of the output terminal 204.
當該開關控制單元106接收到一非休眠信號110(例如一低信號，low signal，或一接地信號)時，該充放電子單元10602對該放電子單元10606放電，且該開關單元104不被導通，使得該輸出端電容204不對該耗能單元102放電。再者，該非休眠信號110可來自於該電子裝置40、該電源供應器20或任何地方；該非休眠信號110代表該電源供應器20將工作在一正常狀態(例如提供電源予該電子裝置40)，該電源供應器20的輸出電壓為一高電壓。該限流子單元10604的一端連接該充放電子單元10602；在一具體實施例，該限流子單元10604的另一端接地即代表該開關控制單元106接收到該非休眠信號110。 When the switch control unit 106 receives a non-sleep signal 110 (eg, a low signal, a low signal, or a ground signal), the charging and discharging electronic unit 10602 discharges the electronic discharge unit 10606, and the switch unit 104 is not The conduction is such that the output capacitor 204 does not discharge the energy consuming unit 102. Moreover, the non-dormant signal 110 can be from the electronic device 40, the power supply 20 or anywhere; the non-sleep signal 110 represents that the power supply 20 will operate in a normal state (eg, providing power to the electronic device 40) The output voltage of the power supply 20 is a high voltage. One end of the current limiting subunit 10604 is connected to the charging and discharging electronic unit 10602. In one embodiment, the other end of the current limiting subunit 10604 is grounded, that is, the switch control unit 106 receives the non-dormant signal 110.
