The phase-shifted full-bridge DC/DC converter is a very important component of power electronics and is suitable for medium and large power output applications based on switching power supplies. Aiming at the implementation of soft-switching and the problem of power loss, this paper firstly describes the structure and working mode of DC/DC converter, then analyzes the calculation and selection process of resonant inductance and capacitance parameters in the converter, and finally adopts the traditional PI control to achieve stable control of the output voltage. The simulation and experimental results fully prove the feasibility and rationality of the design and parameter selection of this scheme.
