電源供應器狀態的判斷方法及其模組 Method for judging power supply state and its module

本發明係有關一種電源供應器狀態的判斷方法及其模組,尤指一種利用功率校正單元穩壓儲能元件電位判斷電源供應器狀態的方法及其模組。 The invention relates to a method for judging the state of a power supply and a module thereof, in particular to a method and a module for determining the state of a power supply by using a power correction unit to stabilize the potential of the energy storage device.

面對科技日益進步的現今,電子裝置(如中央處理器、圖形處理器、硬碟等電子裝置)對電力品質的要求越來越高,輸入電力品質的不穩相對導致電源供應器輸出電力品質不穩,電力品質不穩輕則導致電子裝置效能失常,重則導致電子裝置瞬間失效,除會導致當下運算的數據資料遺失、損毀,更有可能導致電子裝置結構上的損毀。 In the face of the ever-increasing technology, electronic devices (such as central processing units, graphics processors, hard drives and other electronic devices) have higher and higher requirements on power quality. The instability of input power quality leads to the power quality of the power supply. Unstable, the power quality is unstable, which leads to the malfunction of the electronic device. In the meantime, the electronic device will be ineffectively terminated. In addition, the data of the current operation will be lost or damaged, and the structure of the electronic device may be damaged.

為避免電源供應器突然失效造成無法彌補的問題,現今主機板多要求電源供應器提供狀態資訊(俗稱PG訊號、Power Good)以進行管理監控,避免電源供應器突然失效導致前揭問題的發生。主機板接受到標記異常的狀態資訊後,即進行負載降低動作,所謂負載降低動作例如降低風扇轉速,停止對閒置電子裝置的電能供給,藉以避免電源供應器快速失效,於這段時間內,主機板可以對仍在運作中的電子裝置進行關閉。請參閱圖1,圖為習用電源供應器狀態判斷的實施示意圖,一般偵測電源供應器狀態的判斷方法,多是將一判斷模組17電性連接於一電源供應器1的一整流輸出單元16或者是一變壓器13二次側,並同時接受電力以進行狀態判斷,但外部電力需經多級電路(如整流濾波單元11、功因校正單元12、變壓器13一次側等),才會傳導致該整流輸出單元16或該變壓器13二次側,導致判斷反應 時間通常太晚,無法在外部電力源10發生問題的當下時點告知一主機板3供電異常。為此,亦有部分發明人將焦點放在電源供應器3變壓器13一次側前端電路(意指整流濾波單元11、功因校正單元12等)讓檢測結果更符合電源供應器輸入端現況,但電源供應器輸入端通常具高電位的特性,並非所有電子元件皆可承受高電位。此外,電源供應器1並非一定是直流電力輸入,若在交流電力輸入下,判斷模組需增設多級濾波電路消除雜訊,此舉容易導致電路複雜且多級電路的傳遞相對導致反應時間過長,容易產生晚報的問題,且交流電頻率的不同也會導致判斷結果失準的情事發生。另一方面,一般偵測電源供應器狀態的判斷方法僅設一判斷點,常導致外部電力源10稍有變化,便輸出異常訊號,而容易誤判外部電力源10是否確實失效。 In order to avoid irreparable problems caused by the sudden failure of the power supply, today's motherboards require the power supply to provide status information (commonly known as PG signal, Power Good) for management monitoring, to avoid sudden failure of the power supply and cause problems. After receiving the status information of the marked abnormality, the motherboard performs a load reduction operation, such as reducing the fan speed, stopping the power supply to the idle electronic device, and avoiding the rapid failure of the power supply. During this time, the host The board can be turned off for electronic devices that are still in operation. Please refer to FIG. 1 , which is a schematic diagram of the implementation of the state judgment of the conventional power supply. Generally, the method for determining the state of the power supply is to electrically connect a determination module 17 to a rectification output unit of a power supply 1 . 16 or a secondary side of a transformer 13 and simultaneously receiving power for state determination, but the external power needs to pass through a multi-stage circuit (such as the rectification and filtering unit 11, the power factor correction unit 12, the primary side of the transformer 13, etc.) Causing the rectified output unit 16 or the secondary side of the transformer 13 to cause a judgment reaction The time is usually too late to tell a motherboard 3 that the power supply is abnormal when the external power source 10 has a problem. To this end, some inventors have focused on the power supply 3 transformer 13 primary side front-end circuit (meaning rectification filter unit 11, power factor correction unit 12, etc.) to make the test results more in line with the power supply input status, but The power supply input usually has a high potential, and not all electronic components can withstand high potentials. In addition, the power supply 1 is not necessarily a DC power input. If the AC power is input, the judging module needs to add a multi-stage filter circuit to eliminate the noise, which is easy to cause the circuit to be complicated and the multi-stage circuit transmission causes the reaction time to pass. Long, it is easy to produce problems with the evening newspaper, and the difference in the frequency of the alternating current will also lead to the occurrence of inaccurate judgment results. On the other hand, the method for judging the state of the power supply is generally only set to a determination point, which often causes the external power source 10 to change slightly, and then outputs an abnormal signal, and it is easy to misjudge whether the external power source 10 does fail.
