更具體說明，本發明該冗餘式電源供應系統於實施的過程中，該電力整合背板3接受該負載5所輸出的一啟動訊號(Ps_on)後，隨即啟動開機該主電源供應器1以及該副電源供應器2，而該主電源供應器1開機後，其所包含的一第一輸出狀態分析單元11輸出有該第一輕載工作參數或該第一重載工作參數，該副電源供應器2則輸出有該第二輕載工作參數或該第二重載工作參數。於此假設，該輸出比較基準是以該冗餘式電源供應系統輸出電力為50瓦特為基礎，而於一實施例中，該副電源供應器2輸出的該副工作電力為30瓦特低於該輸出比較基準，該副電源供應器2產生有該第二輕載工作參數。而該主電源供應器1輸出的該主工作電力同樣為30瓦特時，該主電源供應器1產生有該第一輕載工作參數。該電力整合背板3的該控制單元31接受到該第一輕載工作參數以及該第二輕載工作參數，令該副電源供應器2 由開機轉為關機，停止轉換該外部電力。然而，關機的該副電源供應器2以該低電壓判斷基準R1比較該穩壓電容器221當下的該穩壓電位V，由於該副電源供應器2停止轉換該外部電力，使該穩壓電容器221無法獲得電力而進入放電狀態，該穩壓電位V持續降低。當該穩壓電位V低於該低電壓判斷基準R1時令該副電源供應器2被短暫重新啟動，該副電源供應器2重新轉換該外部電力，令該穩壓電容器221再次獲得電力而進行充電，且於該暫態工作時間T1(如120ms)後再次關機該副電源供應器2。再者，本發明該電力整合背板3常態受該負載5要求而提供相應功率的電力，若該負載5持續處於低耗能狀態，該電力整合背板3常態使該副電源供應器2常態處於該待命工作模式。如此一來，該副電源供應器2的該穩壓電容器221常態存有電荷，當該電力整合背板3受該負載5要求而需該副電源供應器2輸出電力時，該副電源供應器2無須等待該穩壓電容器221穩壓，即可快速開機啟動提供該副工作電力。又，於一實施例中，該副電源供應器2進入該待命工作模式，更以該放電電壓判斷基準R2判斷該穩壓電位V，於該穩壓電位V低於該放電電壓判斷基準R2後，即令該副電源供應器2上的該隔離電路27斷路，保護該副電源供應器2不受外部電力從其與該電力整合背板3連接的一端進入而產生損壞的問題發生。 More specifically, in the implementation of the redundant power supply system, the power integrated backplane 3 receives a start signal (Ps_on) output by the load 5, and then starts the main power supply 1 and The secondary power supply 2, and after the primary power supply 1 is powered on, a first output state analyzing unit 11 included therein outputs the first light load operating parameter or the first heavy working parameter, the secondary power supply The supplier 2 outputs the second light load operating parameter or the second heavy duty operating parameter. It is assumed herein that the output comparison reference is based on the redundant power supply system output power of 50 watts, and in one embodiment, the secondary power supply 2 outputs the secondary operating power of 30 watts lower than the The comparison reference is output, and the secondary power supply 2 generates the second light load operating parameter. When the main working power output by the main power supply 1 is also 30 watts, the main power supply 1 generates the first light load operating parameter. The control unit 31 of the power integrated backplane 3 receives the first light load operating parameter and the second light load operating parameter, so that the secondary power supply 2 From power on to power off, stop converting the external power. However, the sub power supply 2 that is turned off compares the current regulation potential V of the voltage regulator capacitor 221 with the low voltage determination reference R1, and the voltage regulator capacitor 221 is turned off because the sub power supply 2 stops switching the external power. When the power is not obtained and the discharge state is entered, the steady voltage V continues to decrease. When the regulated potential V is lower than the low voltage determination reference R1, the secondary power supply 2 is briefly restarted, and the secondary power supply 2 re-converts the external power to cause the voltage-stabilizing capacitor 221 to obtain power again. Charging, and shutting down the secondary power supply 2 again after the transient working time T1 (eg, 120 ms). Furthermore, the power integrated backplane 3 of the present invention is normally required to provide power of the corresponding power by the load 5. If the load 5 continues to be in a low power state, the power integrated backplane 3 normally causes the secondary power supply 2 to be in a normal state. In this standby mode of operation. As a result, the voltage regulator capacitor 221 of the secondary power supply 2 normally stores a charge, and when the power integration backplane 3 is required by the load 5 and the secondary power supply 2 needs to output power, the secondary power supply 2 There is no need to wait for the voltage regulator capacitor 221 to stabilize, and the power supply can be provided by the quick start-up. Moreover, in an embodiment, the sub-power supply 2 enters the standby mode of operation, and further determines the regulated potential V by the discharge voltage determination reference R2, after the regulated potential V is lower than the discharge voltage determination reference R2. That is, the isolation circuit 27 on the sub power supply 2 is disconnected, and the problem that the sub power supply 2 is protected from external power from the end to which the power integrated backplane 3 is connected is damaged.
綜上所述，本發明該快速啟動備援的冗餘式電源供應系統，包含有至少一主電源供應器、至少一副電源供應器以及一電力整合背板。該副電源供應器包含一開機啟動後具有一穩壓電位的穩壓電容器，當該副電源供應器受觸發關機而令該穩壓電位低於一低電壓判斷基準時，即進入一待命工作模式，於該待命工作模式中該副電源供應器被重新啟動一暫態工作時間而對該穩壓電容器進行充電。該電力整合背板電性連接該主電源供應 器以及該副電源供應器並常態檢知該主電源供應器及該副電源供應器的輸出狀態而決定該副電源供應器的開機或關機。藉此，以令該副電源供應器常態處於可以快速啟動的待機工作模式上，降低電能的耗費。 In summary, the fast start-up redundant power supply system of the present invention includes at least one main power supply, at least one auxiliary power supply, and a power integrated backplane. The auxiliary power supply comprises a voltage stabilizing capacitor having a voltage stabilizing potential after being turned on, and when the auxiliary power supply is triggered to be turned off and the voltage stabilizing potential is lower than a low voltage determining reference, the standby power supply mode is entered. In the standby mode of operation, the secondary power supply is restarted for a transient operating time to charge the voltage stabilizing capacitor. The power integrated backplane is electrically connected to the main power supply And the secondary power supply and normally detecting the output status of the primary power supply and the secondary power supply to determine whether the secondary power supply is turned on or off. Thereby, the secondary power supply is normally in a standby mode that can be quickly started, and the power consumption is reduced.
