Description
本發明係關於一種電源供應裝置，特別是一種多相電源供應裝置。The present invention relates to a power supply device, and more particularly to a multi-phase power supply device.
傳統單相電源供應裝置可輸出的電流較小，且為了改善暫態響應必須提高切換頻率，然而受限於電晶體的高速特性不佳，因此也會有轉換效率不佳等問題，故在大電流的應用上，多相電源供應裝置取而代之。多相電源供應裝置係將多個單相電源供應單元之輸出並聯，並藉由相位偏移設計使該些單相電源供應單元之輸出波形重疊，藉此使得多相電源供應裝置之運作能像一組以多倍頻率運作的單相電源供應裝置，此時個別電源供應單元之運作頻率僅為該多倍頻率除以運作中之相位數，從而避免了高頻運作所帶來的問題。The traditional single-phase power supply device can output a small current, and the switching frequency must be increased in order to improve the transient response. However, the high-speed characteristic of the transistor is limited, so there is also a problem that the conversion efficiency is not good, so the problem is large. For current applications, multiphase power supplies are replaced. The multi-phase power supply device connects the outputs of the plurality of single-phase power supply units in parallel, and overlaps the output waveforms of the single-phase power supply units by the phase offset design, thereby enabling the operation of the multi-phase power supply device to be A group of single-phase power supply devices operating at multiple frequencies. At this time, the operating frequency of individual power supply units is only the multiple of the frequency divided by the number of phases in operation, thereby avoiding the problems caused by high-frequency operation.
多相電源供應裝置可將欲輸出之總電流分配至各相位(亦即各單相電源供應單元)以輸出，並可因應負載大小而使用一部或全部的電源供應單元來輸出電流，亦即當負載愈重時，多相電源供應裝置會使用更多的電源供應單元來協力輸出更大的電流。然而習知的多相電源供應裝置在選擇電源供應單元來使用時，係直接依據電源供應單元之排列順序來加以選擇，例如當一個八相電源供應裝置欲選擇其中四相來輸出電流時，係直接選擇排列順序中的第1個電源供應單元至排列順序中的第4個電源供應單元來輸出電流，因此會有相鄰的二個或多個電源供應單元同時運作之 情形。即使習知技術未直接依排列順序來選擇電源供應單元以加以使用，習知技術也未曾考慮到避免相鄰的二個或多個電源供應單元同時運作，因此常會出現相鄰的二電源供應單元同時運作、同時產生功率消耗且同時發熱之情形，進而會引發散熱不良等問題。現有技術可參考下列之專利或專利申請案所揭露之內容：美國專利號6154381；台灣專利公告號I307206；台灣專利公開號201216600與中國專利公佈號CN102073364。The multi-phase power supply device can distribute the total current to be output to each phase (that is, each single-phase power supply unit) for output, and can output current using one or all of the power supply units according to the load size, that is, When the load is heavier, the multi-phase power supply unit uses more power supply units to cooperate to output more current. However, the conventional multi-phase power supply device is selected according to the order of arrangement of the power supply units when selecting the power supply unit, for example, when an eight-phase power supply device selects four phases to output current, Directly selecting the first power supply unit in the arrangement order to the fourth power supply unit in the arrangement order to output current, so that two or more adjacent power supply units operate simultaneously situation. Even though the prior art does not directly select the power supply unit for use in the order of arrangement, the prior art does not consider avoiding the simultaneous operation of two or more adjacent power supply units, so that adjacent two power supply units are often present. Simultaneous operation, simultaneous power consumption and simultaneous heat generation, which may cause problems such as poor heat dissipation. The prior art can be referred to the disclosure of the following patents or patent applications: U.S. Patent No. 6,154,381; Taiwan Patent Publication No. I307206; Taiwan Patent Publication No. 201216600 and Chinese Patent Publication No. CN102073364.

請繼續參閱第1圖，本實施例中，若全部第一電源供應單元 112不足以供電予一重載，電源供應單元控制器120會在依據該第一順序致能該些第一電源供應單元112後，進一步依據一第三順序致能複數個第二電源供應單元114之一部分或全部，藉此滿足該重載所需之電力。其中該第三順序可為該第二電源供應單元114之順向或逆向排列順序，或為一隨機順序，又或為其它預定或依條件(例如第二電源供應單元114之溫度)改變之順序。Please continue to refer to FIG. 1 , in this embodiment, if all the first power supply units 112 is insufficient to supply power to a heavy load, and the power supply unit controller 120 further enables the plurality of second power supply units 114 according to a third sequence after enabling the first power supply units 112 according to the first sequence.

請參閱第2圖，其係本發明之多相電源供應器的另一實施例示意圖。第2圖之多相電源供應器200與第1圖所示之多相電源供應器100的主要差異在於：多相電源供應器200進一步包含複數個熱感測器(Thermal Sensor；TS)210，該些熱感測器210分別實體連接該複數個電源供應單元110，用來分別感測該複數個電源供應單元110之發熱情形，並據以輸出複數個感測訊號至電源供應單元控制器120，使電源供應單元控制器120能夠依據該複數個感測訊號來決定或調整該第一順序、該第二順序、該第三順序及該第四順序之一部或全部。Please refer to FIG. 2, which is a schematic view of another embodiment of the multi-phase power supply of the present invention. The main difference between the multi-phase power supply 200 of FIG. 2 and the multi-phase power supply 100 shown in FIG. 1 is that the multi-phase power supply 200 further includes a plurality of thermal sensors (TS) 210, The plurality of power sensors 210 are respectively connected to the plurality of power supply units 110 for sensing the heat generation condition of the plurality of power supply units 110, and outputting a plurality of sensing signals to the power supply unit controller 120. The power supply unit controller 120 can determine or adjust one or all of the first sequence, the second sequence, the third sequence, and the fourth sequence according to the plurality of sensing signals.
承上所述，本實施例中，電源供應單元控制器120係依據複數個感測訊號來判斷複數個電源供應單元110之溫度由低至高的一次序，並依據該次序來決定或調整該第一順序、該第二順序、該第三順序及該第四順序之一部或全部，藉此優先致能複數個電源供應單元110中的溫度低者及/或優先禁能該複數個電源供應單元110中之溫度高者。舉例來說，電源供應單元控制器120依據該次序來決定或調整該第一順序，以依序致能第一電源供應單元112中溫度最低者、溫度次低者、溫度第三低者…溫度最高者；電源供應單元控制器120依據該次序來決定或調整該第二順序，以依序禁能第二電源供應單元114中溫度最高者、溫度次高者、溫度第三高者…溫度最低者；電源供應單元控制器120依據該次序來決定或調整該第三順序，以依序致能第二電源供應單元114中溫度最低者、溫度次低者、溫度第三低者…溫度最高者；以及電源供應單元控制器120依據該次序來決定或調整該第四順序，以依序禁能第一電源供應單元112中溫度最高者、溫度次高者、溫度第三高者…溫度最低者。請注意，本實施例中，電源供應單元控制器120可依感測訊號定時或即時更新該次序及/或被動地依使用者控制來依據感測訊號更新該次序。As described above, in the embodiment, the power supply unit controller 120 determines the order of the temperature of the plurality of power supply units 110 from low to high according to the plurality of sensing signals, and determines or adjusts the order according to the order. One or all of the sequence, the second sequence, the third sequence, and the fourth sequence, thereby preferentially enabling the lower of the plurality of power supply units 110 and/or preferentially disabling the plurality of power supplies The temperature in unit 110 is high. For example, the power supply unit controller 120 determines or adjusts the first sequence according to the order to sequentially enable the lowest temperature of the first power supply unit 112, the second lowest temperature, and the third lowest temperature. The highest; the power supply unit controller 120 determines or adjusts the second sequence according to the order to sequentially disable the highest temperature, the second highest temperature, and the third highest temperature in the second power supply unit 114. The power supply unit controller 120 determines or adjusts the third sequence according to the order to sequentially enable the lowest temperature of the second power supply unit 114, the second lowest temperature, the third lowest temperature, the highest temperature. And the power supply unit controller 120 determines or adjusts the fourth sequence according to the order to sequentially disable the highest temperature, the second highest temperature, the third highest temperature, and the lowest temperature of the first power supply unit 112. .

The implementation of these examples is changed. For example, the power supply unit controller 120 may determine or adjust the first and third sequences only in this order, that is, determine the first power supply unit 112 and the second power supply only in this order. The enabling sequence of the supply unit 114 determines or adjusts the second and fourth modes in a random or predetermined manner; and, for example, the first order determined or adjusted by the power supply unit controller 120 in accordance with the order is in a random or predetermined manner. The lower half of the temperature in the first power supply unit 112 is enabled, and the higher temperature half is enabled in a random or predetermined manner, thereby avoiding the same or similar enabling sequence from occurring again and again. Since there are many possible implementations of variations, it is difficult to cite them one by one, but the foregoing is sufficient to enable those skilled in the art to think of various equal embodiments.
請參閱第3圖，其係本發明之多相電源供應器的又一實施例示意圖。第3圖之多相電源供應器300與第2圖所示之多相電源供應器200的主要差異在於：多相電源供應器300未將複數個電源供應單元110區分為第一電源供應單元及第二電源供應單元。因此，電源供應單元控制器120係依據熱感測器210所提供的複數個感測訊號來判斷複數個電源供應單元110之溫度高低，再依據電源供應單元110之溫度由低至高的一次序來致能複數個電源供應單元110之一第一部分或全部，藉此優先致能複數個電源供應單元110中的溫度低者。舉例來說，電源供應單元控制器120依據該次序致能該第一部分電源供應單元110中的溫度最低者、溫度次低者…溫度最高者。Please refer to FIG. 3, which is a schematic diagram of still another embodiment of the multi-phase power supply of the present invention. The main difference between the multi-phase power supply 300 of FIG. 3 and the multi-phase power supply 200 shown in FIG. 2 is that the multi-phase power supply 300 does not divide the plurality of power supply units 110 into the first power supply unit and Second power supply unit. Therefore, the power supply unit controller 120 determines the temperature of the plurality of power supply units 110 according to the plurality of sensing signals provided by the thermal sensor 210, and then according to the order of the temperature of the power supply unit 110 from low to high. A first portion or all of the plurality of power supply units 110 is enabled, whereby the lower temperature of the plurality of power supply units 110 is preferentially enabled. For example, the power supply unit controller 120 enables the lowest temperature, the second lowest temperature, the highest temperature in the first partial power supply unit 110 according to the sequence.
承上所述，本實施例中，電源供應單元控制器120在致能複數個電源供應單元110之第一部分的同時或之後，如原本電源供應單元110已有一第二部分被致能，電源供應單元控制器120可進一步參考該次序來禁能該第二部分的電源供應單元110，藉此優先禁能當中溫度高者。舉例來說，電源供應單元控制器120依 據該次序禁能該第二部分電源供應單元110中的溫度最高者、溫度次高者…溫度最低者。As described above, in the present embodiment, the power supply unit controller 120 has a second portion enabled, such as the original power supply unit 110, after the first portion of the plurality of power supply units 110 is enabled. The unit controller 120 can further disable the power supply unit 110 of the second portion with reference to the order, whereby the upper temperature is preferentially disabled. For example, the power supply unit controller 120 depends According to the order, the highest temperature, the second highest temperature, and the lowest temperature in the second partial power supply unit 110 are disabled.
另外，於本發明之一較佳實施例中，第3圖的複數個電源供應單元110中可定義出複數個不相鄰接的電源供應單元110，且電源供應單元控制器120可依據前述溫度次序來優先致能該複數個不相鄰接的電源供應單元110，然後再依據該次序致能其它的電源供應單元110之一部或全部。In addition, in a preferred embodiment of the present invention, a plurality of non-adjacent power supply units 110 may be defined in the plurality of power supply units 110 of FIG. 3, and the power supply unit controller 120 may be configured according to the foregoing temperature. The sequence preferentially enables the plurality of non-adjacent power supply units 110, and then enables one or all of the other power supply units 110 in accordance with the sequence.
