Abstract:The small signal model of the phase-shifted full bridge ZVS converter is constructed based on the small signal model of Buck converter. By the analysis of the amplitude frequency characteristic and phase frequency characteristic of the control loop, compensation network of the phase-shifted full bridge ZVS converter is designed to improve the transient response and stability of the system. The rationality of the small signal model and the correctness of the design of the compensation network are verified through simulation.
