中文摘要 早期具有功因校正之AC/DC電力轉換器一般為雙級式,前級為功因校正級,後級為輸出穩壓級,因此需要兩個切換開關,增加成本及電路設計的複雜度。為了改善此缺點,吾人利用元件移位法,將升降壓型與返馳式電力轉換器整合為單級隔離式 HPFC 電力轉換器。再以此單級電路作為基本架構,結合柔性切換技術,設計出新型零電流零電壓轉移(ZCZVT)柔切式高功因AC/DC整流器。
ZCZVT 柔性切換(soft-switching)技術係結合了ZVT與ZCT的優點,有效地提昇電力轉換器之效率。輔助開關在一個切換週期 內切換為on兩次,產生兩次瞬態共振,使主開關達到零電壓切換(ZVS)及零電流切換(ZCS),解決傳統PWM電力轉換器的高切換損失及共振式電力轉換器高電壓/大電流的傳導損失等缺點。
AC/DC電力轉換器,除了須具備有功因校正能力與輸出穩壓之雙重功能外,亦要求bulk電容電壓不受負載變動的影響。經由電路分析可知,當電力轉換器操作在 DCM+DCM 模式時,bulk電容電壓與負載 無關,可避免高電壓應力的問題產生。
本文所探討的電力轉換器,當前級的升降壓型電力轉換器操作在DCM模式時,天生就具有功因校正能力,故無須設計功因校正控制器。此外,為了達到輸出穩壓的要求,吾人應用雙時間尺度平均化法,推導出轉換器於切換週期 下的小信號數學模式,然後再對線電壓週期 作平均化模式推導,並量測電子電路實作之轉移函數,以驗證數學模式之正確性。最後,根據此數學模式,設計輸出穩壓控制器,以降低線電壓及負載變動,對輸出電壓之影響。
英文摘要 The conventional AC/DC converters commonly are composed of two stages. One is power factor correction stage, and the other is output voltage regulation stage. It thereby needs two switches, and thus causes more costs. To overcome the drawback, the components placement is applied to combine buck-boost and flyback converters into a single-stage isolated HPFC converter. On the basis of the single-stage circuit, the soft-switching technology is then applied to design a novel zero-current-zero-voltage-transition (ZCZVT) soft-switching AC/DC rectifier with high power factor correction.
The ZCZVT soft-switching converter exhibits the advantages of both ZVT and ZCT converters. It improves the efficiency of the power converters. To achieve zero voltage switching and zero current switching during switching transitions, the auxiliary switch turns on twice, and thus two resonances occur in one switching period. This converter overcomes the existing problems of high switching losses of the conventional PWM converters and the conduction losses due to high voltage/current stresses of resonance power converters.
The AC/DC power converter must exhibit the ability of power factor correction and output voltage regulation. In addition, the voltage of the bulk capacitor is invariant with the load variations. It reveals from the detailed circuit analysis that the high voltage stress of the bulk capacitor is avoided while the power converter is operating in DCM+DCM mode.
The power converter discussed in this thesis has inherent gift of PFC when buck-boost converter in the first stage is operating in DCM mode. Hence the PFC controller is not needed. Furthermore, The two-time-scale averaging method is used to derive the small-signal mathematical model of the converter in the switching period, and then derive the averaged model in the line period. The theoretical results can be verified with experimental measurements. Finally on the basis of the derived model, an output voltage regulation controller is designed to eliminate the effect of the variations of line voltage and load on the output voltage.
