圖1為根據本發明之電源供應系統之第一實施例之功能方塊圖。在此，圖1係以電源供應系統包含兩個電源供應單元為例。請參照圖1，電源供應系統包含第一電源供應單元11、第二電源供應單元12及控制單元14，兩電源供應單元11、12彼此連接，且控制單元14分別連接於第一電源供應單元11及第二電源供應單元12。兩電源供應單元11、12用以接收一外部電力，例如一市電，兩電源供應單元11、12可將外部電力轉換為直流訊號後向負載15供應電力。在一實施態樣中，負載15可為一電腦裝置或是一伺服器設備中之任何電子組件，例如ATX（Advanced Technology Extended）主機板，電源供應單元11、12可供應ATX主機板需求之不同電位：3.3V、5V及12V。並且，負載15在不同的時間點所需求之電力可能不相同，兩電源供應單元11、12可輸出不同瓦數之電力以符合負載15之需求。於此，兩電源供應單元11、12在不同的時間點可具有不同的負載程度，舉例來說，以兩電源供應單元11、12可輸出之最大功率為500 W為例，當兩電源供應單元11、12均輸出250 W之電力時表示兩電源供應單元11、12的負載值均為50%負載。1 is a functional block diagram of a first embodiment of a power supply system in accordance with the present invention. Here, FIG. 1 is an example in which the power supply system includes two power supply units. Referring to FIG. 1 , the power supply system includes a first power supply unit 11 , a second power supply unit 12 , and a control unit 14 . The two power supply units 11 and 12 are connected to each other, and the control unit 14 is respectively connected to the first power supply unit 11 . And a second power supply unit 12. The two power supply units 11, 12 are configured to receive an external power, such as a mains supply, and the two power supply units 11, 12 can convert the external power into a direct current signal and supply the power to the load 15. In an implementation, the load 15 can be a computer device or any electronic component in a server device, such as an ATX (Advanced Technology Extended) motherboard. The power supply units 11, 12 can supply different ATX motherboard requirements. Potential: 3.3V, 5V and 12V. Moreover, the power required by the load 15 at different points in time may be different, and the two power supply units 11, 12 may output different wattages of power to meet the demand of the load 15. In this case, the two power supply units 11 and 12 can have different load levels at different time points. For example, the maximum power that can be output by the two power supply units 11 and 12 is 500 W, for example, when two power supply units are used. When 11 and 12 are outputting power of 250 W, the load values of the two power supply units 11 and 12 are both 50% load.
進一步，根據兩電源供應單元11、12的不同負載值，兩電源供應單元11、12在不同的時間點亦具有不同的電源轉換效率。圖2為圖1之兩電源供應單元11、12之電源轉換效率之一實施態樣之曲線圖，其中之橫軸及縱軸分別為負載值及電源轉換效率，其兩者皆以百分比（%）表示。由圖2可得知，依據不同的負載值，電源供應單元11、12具有不同的電源轉換效率；並且，相較於較小之負載值（圖2所示例之位於0%負載至20%負載之範圍間，即區間I），較大之負載值（圖2所示例之位於20%負載至80%負載之範圍間）對應於較佳之電源轉換效率。Further, according to different load values of the two power supply units 11, 12, the two power supply units 11, 12 also have different power conversion efficiencies at different time points. 2 is a graph showing an embodiment of the power conversion efficiency of the two power supply units 11 and 12 of FIG. 1, wherein the horizontal axis and the vertical axis are load values and power conversion efficiency, respectively, both in percentage (%) ) said. It can be seen from FIG. 2 that the power supply units 11, 12 have different power conversion efficiencies according to different load values; and, compared with the smaller load values (the example shown in FIG. 2 is located at 0% load to 20% load). Between the ranges, i.e., interval I), a larger load value (between the range of 20% load and 80% load as shown in Fig. 2) corresponds to a preferred power conversion efficiency.
在第一實施例中，第一電源供應單元11可單獨供應負載所需之電力，或是由兩電源供應單元11、12共同分攤負載15所需之電力。詳細而言，第一電源供應單元11及第二電源供應單元12分別具有一順位值，第一電源供應單元11之順位值（為方便描述，以下稱為第一順位值）具有最高之順位序，第二電源供應單元12之順位值（為方便描述，以下稱為第二順位值）之順位序低於第一順位值。在一實施態樣中，第一順位值可為「1」，第二順位值可為「2」或「3」或其他大於「1」之數值。於此，於系統為開機狀態時，具最高順位序（或稱為第一順位序）之第一電源供應單元11不會關閉或進入待命狀態，第一電源供應單元11可單獨供應電力而作為主要之電力供應單元；具較低順位序之第二電源供應單元12係作為次要之電力供應單元，第二電源供應單元12可與第一電源供應單元11共同分攤負載15所需之電力。In the first embodiment, the first power supply unit 11 can separately supply the power required for the load, or the power required by the load 15 can be shared by the two power supply units 11, 12. In detail, the first power supply unit 11 and the second power supply unit 12 respectively have a rank value, and the order value of the first power supply unit 11 (hereinafter referred to as a first order value for convenience of description) has the highest order. The order of the second power supply unit 12 (for convenience of description, hereinafter referred to as the second order value) is lower than the first order value. In an embodiment, the first order value may be "1", and the second order value may be "2" or "3" or other values greater than "1". Here, when the system is in the power-on state, the first power supply unit 11 having the highest order (or referred to as the first order) does not turn off or enters the standby state, and the first power supply unit 11 can separately supply power as The main power supply unit; the second power supply unit 12 having a lower order is used as a secondary power supply unit, and the second power supply unit 12 can share the power required by the load 15 with the first power supply unit 11.
在運作時，控制單元14先分別將第一順位值及第二順位值填入兩電源供應單元11、12，舉例來說，控制單元14可將為「1」之第一順位值填入第一電源供應單元11，並將為「2」之第二順位值填入第二電源供應單元12，使具有第一順位序之第一電源供應單元11可即時地根據不同的電力需求啟動或不啟動第二電源供應單元12。於是，第一電源供應單元11先單獨供應電力，第一電源供應單元11實時（real-time）地比較自身的負載值及一預設控制值，以選擇性地啟動第二電源供應單元12。當第一電源供應單元11判斷其負載值大於預設控制值時，會造成第一電源供應單元11具有較差之電源轉換效率（例如圖2所示之區間II），於是，第一電源供應單元11啟動第二電源供應單元12來共同分攤負載15所需之電力，以使第一電源供應單元11自身的負載值降低，進而提升改善第一電源供應單元11之電源轉換效率回復至具有良好的電源轉換效率，且使第二電源供應單元12同時具有良好之電源轉換效率；另一方面，在第一電源供應單元11單獨供應電力時，當第一電源供應單元11的負載值小於或等於預設控制值時，表示第一電源供應單元11可能已具有良好之電源轉換效率，此時第一電源供應單元11不啟動第二電源供應單元12，以避免負載值降低而落入電源轉換效率較差之範圍間（例如圖2所示之區間I）。In operation, the control unit 14 first fills the first power supply value and the second current value into the two power supply units 11, 12 respectively. For example, the control unit 14 may fill in the first order value of "1". a power supply unit 11 and filling the second power supply unit 12 with the second order value of "2", so that the first power supply unit 11 having the first sequential order can be activated or not according to different power demands in real time. The second power supply unit 12 is activated. Then, the first power supply unit 11 supplies power separately, and the first power supply unit 11 compares its own load value and a preset control value in real-time to selectively activate the second power supply unit 12. When the first power supply unit 11 determines that the load value is greater than the preset control value, the first power supply unit 11 is caused to have poor power conversion efficiency (for example, the interval II shown in FIG. 2), and thus, the first power supply unit 11, the second power supply unit 12 is activated to share the power required by the load 15 to reduce the load value of the first power supply unit 11 itself, thereby improving the power conversion efficiency of the first power supply unit 11 to be restored to have good The power conversion efficiency is such that the second power supply unit 12 has good power conversion efficiency at the same time; on the other hand, when the first power supply unit 11 supplies power separately, when the load value of the first power supply unit 11 is less than or equal to the pre-charge When the control value is set, it indicates that the first power supply unit 11 may have good power conversion efficiency. At this time, the first power supply unit 11 does not activate the second power supply unit 12 to avoid a decrease in the load value and a poor power conversion efficiency. Between the ranges (for example, the interval I shown in Figure 2).
以預設控制值為40%負載且第一電源供應單元11的負載值為82%負載為例說明，第一電源供應單元11在判斷82%負載之負載值大於40%負載之預設控制值後啟動第二電源供應單元12，使第一電源供應單元11自身的負載值下降，此時兩電源供應單元11、12分別具有41%負載之負載值而具有較佳之轉換效率。進一步，當負載15需求之電力減少使兩電源供應單元11、12的負載值由41%負載降低至36%負載時，第一電源供應單元11判斷其負載值（36%負載）小於40%負載之預設控制值，第一電源供應單元11控制第二電源供應單元12待命以單獨供應負載15所需之電力，此時第一電源供應單元11的負載值由36%負載上升至72%負載，於是第一電源供應單元11又再次判斷其負載值（72%負載）大於40%負載之預設控制值而將第二電源供應單元12啟動。基此，第一電源供應單元11反覆地將第二電源供應單元12啟動及待命，第一電源供應單元11具有36%負載或72%負載之負載值而具有較佳之電源轉換效率。Taking the preset control value as a 40% load and the load value of the first power supply unit 11 as an 82% load as an example, the first power supply unit 11 determines that the load value of the 82% load is greater than the preset control value of the 40% load. After the second power supply unit 12 is activated, the load value of the first power supply unit 11 itself is decreased. At this time, the two power supply units 11, 12 respectively have a load value of 41% load and have better conversion efficiency. Further, when the power demand of the load 15 is reduced such that the load value of the two power supply units 11, 12 is reduced from the 41% load to the 36% load, the first power supply unit 11 determines that the load value (36% load) is less than 40% load. The preset power supply unit 11 controls the power required by the second power supply unit 12 to separately supply the load 15, and the load value of the first power supply unit 11 rises from 36% load to 72% load. Then, the first power supply unit 11 again determines that the load value (72% load) is greater than the preset control value of the 40% load and activates the second power supply unit 12. Accordingly, the first power supply unit 11 repeatedly activates and stands by the second power supply unit 12, and the first power supply unit 11 has a load value of 36% load or 72% load and has better power conversion efficiency.
承上，以預設控制值為40%負載為例，在另一情形中，當第一電源供應單元11單獨啟動且其負載值為30%負載時，第一電源供應單元11判斷30%負載之負載值小於40%負載之預設控制值，此時第一電源供應單元11不啟動第二電源供應單元12，第一電源供應單元11之負載值為30%負載而具有較佳之電源轉換效率。在其他實施態樣中，預設控制值亦可為40%負載以外之其他百分比值，例如20%負載、50%負載，本發明不以此為限。For example, in the case where the preset control value is 40% load, in another case, when the first power supply unit 11 is individually started and its load value is 30% load, the first power supply unit 11 determines 30% load. The load value is less than the preset control value of the load of 40%. At this time, the first power supply unit 11 does not activate the second power supply unit 12, and the load value of the first power supply unit 11 is 30% load and has better power conversion efficiency. . In other implementations, the preset control value may also be other percentage values than the 40% load, such as 20% load, 50% load, and the invention is not limited thereto.
在一實施態樣中，為避免第一電源供應單元11反覆地控制第二電源供應單元12啟動及待命，前述之預設控制值包含一上限值及一下限值，第一電源供應單元11可分別根據前述之上限值及下限值來判斷是否控制第二電源供應單元12啟動或待命。詳細而言，在第一電源供應單元11單獨啟動的情形中，第一電源供應單元11係比較其自身之負載值與上限值，當其負載值大於上限值時，第一電源供應單元11始啟動第二電源供應單元12；在第一電源供應單元11與第二電源供應單元12同時啟動之情形中，第一電源供應單元11係比較其負載值與下限值，當其負載值等於或小於下限值時，第一電源供應單元11始控制第二電源供應單元12待命。In an implementation manner, in order to prevent the first power supply unit 11 from repeatedly controlling the startup and standby of the second power supply unit 12, the preset control value includes an upper limit value and a lower limit value, and the first power supply unit 11 Whether or not to control the second power supply unit 12 to be activated or standby may be determined based on the foregoing upper limit value and lower limit value, respectively. In detail, in the case where the first power supply unit 11 is separately activated, the first power supply unit 11 compares its own load value and the upper limit value, and when the load value thereof is greater than the upper limit value, the first power supply unit 11 starts the second power supply unit 12; in the case where the first power supply unit 11 and the second power supply unit 12 are simultaneously activated, the first power supply unit 11 compares the load value and the lower limit value thereof, when the load value thereof When it is equal to or less than the lower limit value, the first power supply unit 11 initially controls the second power supply unit 12 to stand by.
舉例來說，以前述之上限值及下限值分別為40%負載及20%負載為例，當第一電源供應單元11單獨啟動且其負載值為60%時，第一電源供應單元11判斷其負載值大於為40%負載之上限值，此時第一電源供應單元11啟動第二電源供應單元12。在第二電源供應單元12啟動後，第一電源供應單元11的負載值由60%負載下降至30%，此時第一電源供應單元11比較其負載值與下限值且判斷出其負載值並未小於為20%負載之下限值，第一電源供應單元11並不控制第二電源供應單元12待命，直到負載15需求之電力減少而致使第一電源供應單元11的負載值由30%負載下降至20%負載時，第一電源供應單元11始判斷出其負載值等於下限值而控制第二電源供應單元12待命。For example, taking the above upper limit value and the lower limit value as 40% load and 20% load, respectively, when the first power supply unit 11 is separately activated and its load value is 60%, the first power supply unit 11 It is judged that the load value is greater than the upper limit of 40% load, at which time the first power supply unit 11 activates the second power supply unit 12. After the second power supply unit 12 is started, the load value of the first power supply unit 11 is reduced from 60% load to 30%, at which time the first power supply unit 11 compares its load value with the lower limit value and determines its load value. Not less than the lower limit of 20% load, the first power supply unit 11 does not control the second power supply unit 12 to stand by until the power required by the load 15 decreases to cause the load value of the first power supply unit 11 to be 30%. When the load drops to 20% load, the first power supply unit 11 first determines that its load value is equal to the lower limit value and controls the second power supply unit 12 to stand by.
在一實施態樣中，電源供應單元11、12之間係經由電源背板（backplane）系統16彼此連接，且電源供應單元11、12中之每一者包含一控制晶片。於此，具順位序為最高之電源供應單元例如，第一電源供應單元11之控制晶片可實時地比較自身之負載值與預設控制值，當負載值大於預設控制值時，第一電源供應單元11的控制晶片可經由電源背板系統16中之線路啟動第二電源供應單元12，當負載值小於或等於預設控制值時，前述之控制晶片亦可藉由電源背板系統16中之線路控制第二電源供應單元12待命。並且，如圖1所示，控制單元14連接於電源背板系統16。控制單元14藉由電源背板系統16分別連接於第一電源供應單元11及第二電源供應單元12，控制單元14可經由電源背板系統16中之線路將兩順位值分別填入兩電源供應單元11、12。在一實施態樣中，控制單元14可為一基板管理控制器（Baseboard Management Controller；BMC）。In one embodiment, the power supply units 11, 12 are connected to each other via a power backplane system 16, and each of the power supply units 11, 12 includes a control wafer. Here, the power supply unit having the highest order is, for example, the control chip of the first power supply unit 11 can compare its own load value and the preset control value in real time, and when the load value is greater than the preset control value, the first power source The control chip of the supply unit 11 can activate the second power supply unit 12 via a line in the power backplane system 16, and the control chip can also be used in the power backplane system 16 when the load value is less than or equal to a preset control value. The line controls the second power supply unit 12 to stand by. Also, as shown in FIG. 1, control unit 14 is coupled to power backplane system 16. The control unit 14 is respectively connected to the first power supply unit 11 and the second power supply unit 12 by the power backplane system 16, and the control unit 14 can fill the two power supply values respectively through the lines in the power backplane system 16. Units 11, 12. In an implementation, the control unit 14 can be a Baseboard Management Controller (BMC).
在一實施態樣中，電源供應單元11、12包含各項參數，控制單元14可設定電源供應單元11、12的各項參數。舉例來說，控制單元14可設定電源供應單元11、12的備援功能，以將電源供應單元11、12的備援功能設定為啟用（enable）或停用（disable）。當電源供應單元11、12的備援功能均為啟用時，控制單元14可進一步設定電源供應單元11、12的順位值，使第一電源供應單元11具有第一順位序而可根據自身的負載值選擇性地啟動第二電源供應單元12；當兩電源供應單元11、12中之一者或其他電源供應單元的備援功能為停用時，備援功能為停用之電源供應單元總是處於啟動狀態，具第一順位序之電源供應單元並無法將備援功能為停用之電源供應單元關閉或是使其待命。In an embodiment, the power supply unit 11, 12 includes various parameters, and the control unit 14 can set various parameters of the power supply unit 11, 12. For example, the control unit 14 can set the backup function of the power supply units 11, 12 to set the backup function of the power supply units 11, 12 to enable or disable. When the backup functions of the power supply units 11, 12 are all enabled, the control unit 14 may further set the order value of the power supply units 11, 12 so that the first power supply unit 11 has the first order and can be loaded according to its own load. The value selectively activates the second power supply unit 12; when the backup function of one of the two power supply units 11, 12 or other power supply unit is disabled, the backup function is the deactivated power supply unit In the startup state, the power supply unit with the first sequential order cannot turn off or enable the backup power supply unit for the deactivated power supply unit.
於此，如圖1所示，電源供應系統更包含一基本輸出輸入系統（BIOS）記憶體17耦接於控制單元14。控制單元14可在開機階段中根據BIOS設定來設定電源供應單元11、12的各項參數。當電源供應單元11、12的備援功能在BIOS設定中為啟用時，控制單元14根據BIOS設定將一致能值（例如，「1」）經由電源背板系統16填入電源供應單元11、12；進一步，當電源供應單元11、12的備援功能在BIOS設定中均為啟用時，控制單元14可根據BIOS設定進一步藉由電源背板系統16將兩順位值（例如，「1」、「2」，或是「3」、「5」）分別填入電源供應單元11、12；另一方面，當電源供應單元11、12中之任一者的備援功能在BIOS設定為停用時，控制單元14根據BIOS設定將一禁能值（例如，「0」）經由電源背板系統16填入電源供應單元11、12中備援功能為停用之電源供應單元。As shown in FIG. 1 , the power supply system further includes a basic output input system (BIOS) memory 17 coupled to the control unit 14 . The control unit 14 can set various parameters of the power supply units 11, 12 in accordance with BIOS settings during the booting phase. When the backup function of the power supply units 11, 12 is enabled in the BIOS setting, the control unit 14 fills the power supply unit 11, 12 via the power backplane system 16 according to the BIOS setting. Further, when the backup function of the power supply units 11, 12 is enabled in the BIOS setting, the control unit 14 can further adjust the two-bit value by the power backplane system 16 according to the BIOS setting (for example, "1", " 2", or "3", "5") are respectively filled in the power supply units 11, 12; on the other hand, when the backup function of any of the power supply units 11, 12 is set to be disabled in the BIOS The control unit 14 fills a disable value (for example, “0”) into the power supply units 11 and 12 via the power supply backplane system 16 according to the BIOS setting, and the backup function is a deactivated power supply unit.
在一實施態樣中，使用者可藉由BIOS開機設定選單改變電源供應單元11、12的各項參數，例如，使用者可自行選擇電源供應單元中哪一些電源供應單元的備援功能為啟用，而哪一些電源供應單元的備援功能為停用，且使用者亦可藉由BIOS開機設定選單自行設定每一電源供應單元的順位值。於是，在電腦裝置或是伺服器重新啟動時，控制單元14可在開機階段中根據BIOS設定自動將致能值及不同之順位值分別填入受使用者選擇而備援功能為啟用之電源供應單元，並將禁能值填入受使用者選擇而備援功能為停用之電源供應單元。In an embodiment, the user can change various parameters of the power supply unit 11 and 12 by using the BIOS startup setting menu. For example, the user can select which of the power supply units in the power supply unit is enabled. And the backup function of some power supply units is disabled, and the user can also set the order value of each power supply unit by using the BIOS boot setting menu. Therefore, when the computer device or the server is restarted, the control unit 14 can automatically fill in the enable value and the different order value according to the BIOS setting in the booting phase, respectively, into the power supply that is selected by the user and the backup function is enabled. The unit, and the disabled value is filled in the power supply unit that is selected by the user and the backup function is disabled.
圖3為根據本發明之電源供應系統之第二實施例之功能方塊圖。在此，圖3係以三個電源供應單元為例，然本發明不以此為限，電源供應單元的數量亦可為四或是大於四。請參照圖3，電源供應系統更包含第三電源供應單元13，第三電源供應單元13經由電源背板系統16分別連接於兩電源供應單元11、12及控制單元14。在第二實施例中，電源供應單元11-13的備援功能可為啟用或停用，當電源供應單元11-13的備援功能為啟用時，控制單元14將三個順位值分別填入電源供應單元11-13。以電源供應單元11、12分別具有最高順位序與次高之順位序為例，第三電源供應單元13的順位序低於第一順位值及第二順位值而具有最低之順位序。在一實施態樣中，電源供應單元11、12、13之順位值可分別為「1」、「2」、「3」，或者，第三電源供應單元13之順位值亦可為大於「1」、「2」之其他數值。3 is a functional block diagram of a second embodiment of a power supply system in accordance with the present invention. Here, FIG. 3 is exemplified by three power supply units. However, the present invention is not limited thereto, and the number of power supply units may be four or more. Referring to FIG. 3 , the power supply system further includes a third power supply unit 13 , and the third power supply unit 13 is respectively connected to the two power supply units 11 , 12 and the control unit 14 via the power backplane system 16 . In the second embodiment, the backup function of the power supply unit 11-13 may be enabled or disabled. When the backup function of the power supply unit 11-13 is enabled, the control unit 14 fills in three consecutive values. Power supply unit 11-13. For example, the power supply units 11 and 12 respectively have the highest order and the next highest order. The third power supply unit 13 has a lower order than the first order value and the second order value and has the lowest order. In one embodiment, the power supply units 11, 12, and 13 may have a value of "1", "2", or "3", respectively, or the third power supply unit 13 may have a value greater than "1". "," other values of "2".
在運作時，第一電源供應單元11先單獨提供電力，電源供應單元12-13可操作於待機模式，第一電源供應單元11根據自身的負載值選擇性地啟動電源供應單元12、13。以預設控制值為40%負載且第一電源供應單元11的負載值為84%負載為例，此時第一電源供應單元11判斷為84%負載之負載值大於為40%負載之預設控制值，第一電源供應單元11依據電源供應單元12、13之順位序將電源供應單元12、13中具有較高順位序之第二電源供應單元12啟動；於是，第一電源供應單元11的負載值由84%負載降低至42%負載，此時第一電源供應單元11判斷為42%負載之負載值大於為40%負載之預設控制值，第一電源供應單元11將順位序低於第二電源供應單元12之第三電源供應單元13啟動，於是，第一電源供應單元11的負載值由42%負載降低至28%負載，此時電源供應單元12、13同時具有28%負載之負載值，電源供應單元11、12、13均具有較佳之電源轉換效率。In operation, the first power supply unit 11 separately supplies power, the power supply unit 12-13 is operable in a standby mode, and the first power supply unit 11 selectively activates the power supply units 12, 13 according to its own load value. Taking the preset control value as 40% load and the load value of the first power supply unit 11 as an example of 84% load, the first power supply unit 11 determines that the load value of the 84% load is greater than the preset value of 40% load. Control value, the first power supply unit 11 activates the second power supply unit 12 having a higher order in the power supply units 12, 13 according to the order of the power supply units 12, 13; thus, the first power supply unit 11 The load value is reduced from the 84% load to the 42% load. At this time, the first power supply unit 11 determines that the load value of the 42% load is greater than the preset control value of the 40% load, and the first power supply unit 11 will lower the order. The third power supply unit 13 of the second power supply unit 12 is activated, so that the load value of the first power supply unit 11 is reduced from 42% load to 28% load, at which time the power supply units 12, 13 have 28% load at the same time. The load value, the power supply units 11, 12, 13 all have better power conversion efficiency.
另一方面，在第一電源供應單元11將電源供應單元12、13中具較高順位值之第二電源供應單元12啟動之後，當第一電源供應單元11的負載值已小於或等於預設控制值，此時第一電源供應單元11並不進一步將第三電源供應單元13啟動。舉例來說，以第一電源供應單元11單獨供應電力且其負載值為64%負載為例，第一電源供應單元11在將第二電源供應單元12啟動後判斷為32%負載之負載值小於為40%負載之預設控制值，此時第一電源供應單元11不將第三電源供應單元13啟動，電源供應單元11、12同時具有32%負載之負載值，電源供應單元11、12均具有較佳之電源轉換效率。On the other hand, after the first power supply unit 11 starts the second power supply unit 12 having a higher order value among the power supply units 12, 13, when the load value of the first power supply unit 11 is less than or equal to the preset The control value, at this time, the first power supply unit 11 does not further activate the third power supply unit 13. For example, taking the first power supply unit 11 separately supplying power and having a load value of 64% load as an example, the first power supply unit 11 determines that the load value of the 32% load is less than after the second power supply unit 12 is started. The preset control value of the 40% load, at which time the first power supply unit 11 does not activate the third power supply unit 13, the power supply units 11, 12 have a load value of 32% load at the same time, and the power supply units 11, 12 are both Has better power conversion efficiency.
進一步，在第一電源供應單元11將電源供應單元12、13依序啟動之後，當負載15所需之電力降低使第一電源供應單元11的負載值低於預設控制值時，第一電源供應單元11根據電源供應單元12、13之順位值先控制電源供應單元12、13中具有較低順位序之第三電源供應單元13待命，並在第三電源供應單元13待命後，第一電源供應單元11比較自身的負載值與預設控制值，當其負載值小於或等於預設控制值時，第一電源供應單元11進一步控制第二電源供應單元12待命；當其負載值轉為大於預設控制值時，第一電源供應單元11不控制第二電源供應單元12待命而是將第三電源供應單元13再次啟動。Further, after the first power supply unit 11 sequentially starts the power supply units 12, 13, when the power required by the load 15 decreases so that the load value of the first power supply unit 11 is lower than a preset control value, the first power source The supply unit 11 first controls the third power supply unit 13 having the lower order in the power supply units 12, 13 to be on standby according to the order value of the power supply units 12, 13, and after the third power supply unit 13 stands by, the first power supply The supply unit 11 compares its own load value with a preset control value. When the load value is less than or equal to the preset control value, the first power supply unit 11 further controls the second power supply unit 12 to stand by; when its load value turns to be greater than When the control value is preset, the first power supply unit 11 does not control the second power supply unit 12 to stand by but starts the third power supply unit 13 again.
舉例來說，以第一電源供應單元11的負載值為36%負載且電源供應單元11、12、13三者皆為啟動為例，當第一電源供應單元11判斷出為36%負載之負載值小於為40%負載之預設控制值時，第一電源供應單元11先控制第三電源供應單元13待命，使第一電源供應單元11的負載值由36%負載上升至54%負載，此時為54%負載之負載值大於為40%負載之預設控制值，第一電源供應單元11不控制第二電源供應單元12待命，且第一電源供應單元11再次將第三電源供應單元13啟動，此後第一電源供應單元11將反覆地啟動並控制第三電源供應單元13待命，或是根據預設控制值之上限值或下限值控制第三電源供應單元13啟動或關閉，於此不再贅述。於是，電源供應單元11、12同時具有54%負載之負載值或是電源供應單元11-13同時具有36%負載之負載值，使電源供應單元12-13中之啟動者具有較佳之電源轉換效率。For example, the load value of the first power supply unit 11 is 36% load and the power supply units 11, 12, 13 are all started. When the first power supply unit 11 determines that the load is 36% load. When the value is less than the preset control value of 40% load, the first power supply unit 11 first controls the third power supply unit 13 to stand by, so that the load value of the first power supply unit 11 is increased from 36% load to 54% load. When the load value of the 54% load is greater than the preset control value of 40% load, the first power supply unit 11 does not control the second power supply unit 12 to stand by, and the first power supply unit 11 again supplies the third power supply unit 13 Startup, after which the first power supply unit 11 will repeatedly start and control the third power supply unit 13 to stand by, or control the third power supply unit 13 to be turned on or off according to the upper limit value or the lower limit value of the preset control value. This will not be repeated here. Therefore, the power supply unit 11, 12 has a load value of 54% load at the same time or the power supply unit 11-13 has a load value of 36% load at the same time, so that the initiator in the power supply unit 12-13 has better power conversion efficiency. .
在第二實施例中，控制單元14亦可根據BIOS設定來啟用或停用第三電源供應單元13的備援功能。當第三電源供應單元13的備援功能為停用時，控制單元14可根據BIOS設定將禁能值填入第三電源供應單元13；當第三電源供應單元13的備援功能為啟用時，控制單元14可根據BIOS設定來填入第三電源供應單元13的順位值，且使用者可透過BIOS開機設定選單修改第三電源供應單元13的各項參數，於此不再贅述。In the second embodiment, the control unit 14 can also enable or disable the backup function of the third power supply unit 13 according to the BIOS settings. When the backup function of the third power supply unit 13 is deactivated, the control unit 14 may fill the disable value into the third power supply unit 13 according to the BIOS setting; when the backup function of the third power supply unit 13 is enabled The control unit 14 can fill in the value of the third power supply unit 13 according to the BIOS setting, and the user can modify the parameters of the third power supply unit 13 through the BIOS startup setting menu, and details are not described herein.
綜上所述，根據本發明之電源供應系統之一實施例，複數電源供應單元中具有最高順位序之電源供應單元可根據負載對電力之不同需求選擇性地啟動具有較低順位序之電源供應單元，使每一啟動之電源供應單元具有較佳之電源轉換效率而減少熱損耗，進而提高電源供應器之壽命及穩定度。再者，BIOS設定中的每一電源供應單元的參數可儲存在BIOS記憶體中，使用者可在BIOS之開機設定選單中選擇分別將BIOS設定中每一電源供應單元的備援功能啟用或停用，使系統在重新開機後可自動根據BIOS設定中的每一電源供應單元的參數設定每一電源供應單元，使用者毋須以手動編碼之方式重新設定每一電源供應單元，大幅地提升使用上之便利性且解決人為疏失之潛在問題。In summary, according to an embodiment of the power supply system of the present invention, the power supply unit having the highest order in the plurality of power supply units can selectively activate the power supply with a lower order according to the different demands of the load on the power. The unit enables each of the activated power supply units to have better power conversion efficiency and reduce heat loss, thereby improving the life and stability of the power supply. Furthermore, the parameters of each power supply unit in the BIOS setting can be stored in the BIOS memory, and the user can select to enable or disable the backup function of each power supply unit in the BIOS setting in the BIOS boot setting menu. Therefore, after the system is restarted, each power supply unit can be automatically set according to the parameters of each power supply unit in the BIOS setting, and the user does not need to manually reset each power supply unit by manual coding, thereby greatly improving the use. Convenience and address potential problems of human error.
