摘　　要：无最小电压应力 (NMVS)的PWM变换器与有最小电压应力的PWM变换器相比 ,具有电流应力小、效率高等突出优点。具体给出了无最小电压应力的无源无损软开关在功率因数校正电路中的设计方法 。The PWM converter with non minimum voltage stress (NMVS) compared to another with minimum voltage stress has many merits such as smaller current stress and higher efficiency and so on. This paper proposes the design method of the lossless and passive soft switching applied in the power factor correction circuits. Its efficiency is proved by simulation results.
