| Abstract: | The ZVZCS phase-shifting full bridge PWM converter achieves ZVS of the leading-leg and ZCS of the lagging-leg,which structure is simple,duty cycle loss is small,soft switching is easy to implement and so on.This paper analyzes its principle from all around,discusses the condition of achieving soft switching,designs main parameters and simulates it by using SIMetrix software.The results prove that parameters are designed reasonably and this converter can achieves ZVZCS. |
