The analysis and design of high power phase-shifted full bridge switching power supply are presented in this paper.The paper firstly introduces present situation of switching power supply,and then analyzes the operating principle of phase-shifted full bridge converter and the realization of soft switching techniques.Soft switching can reduce switching loss and increase circuit efficiency.Integrated design of power supply system and each component circuit are also proposed.The experiment results demonstrate that the power supply device satisfies design requirements completely.It has been applied in the electric plating production line successfully.
