Description

高功率電源供應器之電路結構 Circuit structure of high power power supply

本發明係屬於電源供應設備之技術領域，特別是關於一種高功率電源供應器之電路結構，以利用二次側採用諧振式轉換器(LLC Converter)搭配同步整流器(Synchronous Rectifier,SR Rect.)的電路架構提升整體電源的能量轉換效率。 The invention belongs to the technical field of power supply equipment, and particularly relates to a circuit structure of a high-power power supply. The secondary side uses a LLC converter with a synchronous rectifier (SR Rect.). The circuit architecture improves the energy conversion efficiency of the overall power supply.

對於廣泛的輸入電壓範圍和高輸出電流的應用而言，切換式電源供應設備(Switch Power Supply,SPS)較線性穩壓設備相比，係具有顯著的高效率優勢而呈現較強勁的市場應用性，而其常見的電路架構不外乎有返馳式(Flyback)、降壓式(Buck)、升壓式(Boost)、順向式(Forward)及推挽式(Push-pull)等。舉例而言，如圖1所示，現行具多組輸出電壓功能之電源供應器1可由一電磁濾波器(EMI Filter)10、一橋式整流器11、一功因校正轉換器(Power Factor Corrector Converter,PFC Converter)12、一LLC Converter 13、一SR Rect. 14、至少一降壓器15與一返馳式轉換器16所構成，且該橋式整流器11電性連接該EMI Filter 10與該PFC Converter 12，該LLC Converter 13電性連接該PFC Converter 12、該SR Rect. 14與該返馳式轉換器16，該SR Rect. 14電性連接該降壓器15。該橋式整流器11透過該EMI Filter 10承接一輸入電壓並整流形成一整流電壓，以使該PFC Converter 12進行功率校正而形成一轉換電壓後提供予該LLC Converter 13與該返馳式轉換器16，並且，該LLC Converter 13與該返馳式轉換器16分別利用該轉換電壓輸出一初級電壓與5Vsb(伏特)/2.01A(安培)之一次級電壓。又，該LLC Converter 13透過該SR Rect. 14整流輸出12V/58.85A 之一第一初級電壓，與透過複數使用型態之該等降壓器15降壓輸出5V/18.19A一第二初級電壓與3.3V/18.19A一第三初級電壓。如此，該橋式整流器11、該PFC Converter 12、該LLC Converter 13、輸出5V之該降壓器15、輸出3.3V之該降壓器15與該返馳式轉換器16之能量轉換效率(Eff)將如下表(一)所示。 For applications with a wide range of input voltages and high output currents, compared to linear regulators, Switch Power Supply (SPS) has a significant high efficiency advantage and presents a stronger market applicability And its common circuit architecture is nothing more than Flyback, Buck, Boost, Forward and Push-pull. For example, as shown in FIG. 1, the current power supply 1 with multiple output voltage functions may include an EMI Filter 10, a bridge rectifier 11, and a Power Factor Corrector Converter. PFC Converter) 12, an LLC Converter 13, an SR Rect. 14, at least one step-down converter 15 and a flyback converter 16, and the bridge rectifier 11 is electrically connected to the EMI Filter 10 and the PFC Converter 12, the LLC Converter 13 is electrically connected to the PFC Converter 12, the SR Rect. 14 and the flyback converter 16, and the SR Rect. 14 is electrically connected to the step-down 15. The bridge rectifier 11 receives an input voltage through the EMI Filter 10 and rectifies to form a rectified voltage, so that the PFC Converter 12 performs power correction to form a converted voltage and then provides it to the LLC Converter 13 and the flyback converter 16 Moreover, the LLC Converter 13 and the flyback converter 16 respectively use the converted voltage to output a primary voltage and a secondary voltage of 5Vsb (volts) /2.01A (amps). In addition, the LLC Converter 13 rectifies and outputs 12V / 58.85A through the SR Rect. 14 One of the first primary voltages and 5V / 18.19A-a second primary voltage and 3.3V / 18.19A-a third primary voltage are stepped down by the step-down devices 15 of a plurality of use types. In this way, the energy conversion efficiency of the bridge rectifier 11, the PFC Converter 12, the LLC Converter 13, the step-down 15 outputting 5V, the step-down 15 outputting 3.3V, and the flyback converter 16 (Eff ) Will be shown in the following table (a).

該電源供應器1可謂透過後級之該LLC Converter 13與該返馳式轉換器16磁感該轉換電壓而形成多組輸出電壓的功能。同時，利用該返馳式轉換器16經迴授穩定後產出一工作電壓給於PFC Converter 12進行功因調控後實現輸出電壓的穩定性。不過，於此架構中，第一初級電壓降壓形成5Vsb之該次級電壓僅呈現約80%的能量轉換效率，換言之，當該次級電壓與該初級電壓之壓值差異越大時，該次級電壓之能量轉換效率將越低落而不符合時下環保綠能的發展趨勢。並且，為利用該初級電壓轉換形成不同壓值之輸出電壓，該電源供應器1係採用於該SR Rect. 14後端增置複數型態之該降壓器15之電路架構，除影響能量轉換效率外，更使整體電路結構的複雜度大幅增加而不利產品微型化。有感於此，如何改良該電源供應器1之電路架構，以於提供多組穩定輸出電壓的同時提升能量轉換效率，即為本發明所亟欲探究之課題。 The power supply 1 can be described as a function of forming multiple sets of output voltages through the LLC Converter 13 and the flyback converter 16 in the subsequent stage to magnetically sense the conversion voltage. At the same time, the flyback converter 16 is used to output a working voltage to the PFC Converter 12 for power factor regulation after feedback stabilization to achieve output voltage stability. However, in this architecture, the first primary voltage is reduced to 5Vsb, and the secondary voltage only exhibits an energy conversion efficiency of about 80%. In other words, when the difference between the secondary voltage and the primary voltage is greater, the The lower the energy conversion efficiency of the secondary voltage, the lower the current trend of environmental protection and green energy. In addition, in order to use the primary voltage conversion to form output voltages of different voltage values, the power supply 1 uses a circuit architecture of the step-down 15 with a complex type added to the back end of the SR Rect. 14 except for affecting energy conversion. In addition to efficiency, the complexity of the overall circuit structure is greatly increased, which is not conducive to miniaturization of the product. In view of this, how to improve the circuit architecture of the power supply 1 so as to provide multiple sets of stable output voltages while improving energy conversion efficiency is a subject that the present invention is desperately exploring.
