中文摘要：
研究了一种具有双极性增益特性的变换器。通过调节占空比可以得到正极性电压增益或负极性电压增益,该变换器可以作为功率因数校正变换器,省去了前端二极管整流桥,从而减小了导通路径损耗,提升了效率。论文分析了该双电感双极性增益变换器工作于电感电流连续模式时的工作模态,分析了正负电压增益情况下的直流稳态特性。分析结果表明该双电感双极性增益变换器能够实现双极性增益,具有输入电流连续等优点。最后,搭建实验平台验证了理论分析的正确性。
英文摘要：
Active Power Factor Correction（ APFC） has been widely used in power electronic circuits for it can improve the power factor,reduce the harmonic pollution of grid,reduce the conduction loss and save energy. But in diode rectifier bridge of the conventional PFC circuit there exists a relatively large amount of conduction loss,therefore many bridgeless PFC circuits have been proposed. This paper focused on a novel converter which has the character of both positive and negative voltage gain by adjusting the duty cycle,thus leaving out the diode rectifier bridge as the active power factor correction（ APFC） circuit,reducing the conduction loss,and raising the efficiency. The continuous conduction mode（ CCM） operation and the steady state characteristics in both positive and negative voltage gain are analyzed in this paper. Analysis shows that the two-inductor bipolar gain converter can achieve bipolar voltage gain,and has the characteristic of continuous input current. Experimental platform was built to verify the correctness of the analysis.
