摘　　要：研究了一种非最小电压应力无源无损PWM变换器,与具有最小电压应力的PWM变换器相比,它具有电流应力更小、效率更高的优势。分析了非最小电压应力的无源无损电路网络在无桥Dual-Boost功率因数矫正(Power Factor Correction,PFC)的工作模态,并且给出了相应的参数设计。仿真结果证实了方案的可行性。A non-minimum voltage stress lossless passive soft-switching converter is analyzed. Comparing the PWM converter with minimum voltage stress, it has the characteristics of smaller current stress and higher efficien- cy. Furthermore, a novel bridgeless dual-boost power factor correction converter which has the characteristics of non-minimum voltage stress lossless passive soft-switching is proposed and analysis its operational principle. Also responding parameter design is described. Computer simulation results verify the feasibility of the converter.
