Abstract:

A phase-shifted full-bridge soft-switching converter with synchronous rectification function suitable for low-voltage and high-current applications was studied by this paper.The soft switching technology is used to reduce the switching loss of the circuit,and the synchronous rectification technology is used to reduce the rectification loss of the circuit,which effectively improves the efficiency of the converter.The soft switching technology and synchronous rectifier circuit in phase shift full-bridge inverter were analyzed.

Key words: phase-shift full bridge inverter, soft switching, synchronous rectifier, switching loss
