Abstract :
An improved phase-shifted zero-voltage and zero-current switching PWM power converter (PS-ZVZCS-PWM converter) is proposed, which achieves zero-voltage-switching of the leading leg and zero-current-switching of the lagging leg. The saturable inductor and the anti-paralleled diodes of the lagging leg in the previous PS-ZVZCS-PWM power converter are removed and this avoids the corresponding drawbacks such as secondary duty loss and the loss of the saturable inductor. The operation of the new power converter is analyzed and simulation results are also presented
