摘 要：
This paper adopts the full-bridge phase-shift DC/DC converter which has the function of realizing zero voltage switching into power electronic transformer,analyses the functions of every part and uses proper control strategy.The simulation results showed that this converter could still realize the function of soft-switching in PET and it was appropriate to work in high frequency state to reduce the size and improve the efficiency of the device.The simulation waveform input current and output voltage of PET were in good condition,which proves that PET has the ability of dealing with power quality problem such as voltage fluctuation and web side harmonic as well as realizing voltage level transformation and energy transfer.
