| Abstract: | This paper investigates Non Minimum Voltage Stress(NMVS) passive lossless snubber circuits in Pulse Width Modulated(PWM) converters.Compared to active soft switching,the presented circuits are simple and can be operated easily.Compared to Minimum Voltage Stress(MVS) passive lossless snubber circuits,the NMVS passive lossless snubber circuits have less current stress,wider soft switching range and higher efficiency. |
