摘要

On the basis of the analysis of phase-shifted full-bridge ZVS PWM converter, Corresponding small-signal model is build using of state-space averaging method and the traditional Buck circuit model, Thereof control block diagram of the system and transfer function are derived, Voltage single-loop control system is designed on the basis of small-signal model of phase-shifted full-bridge ZVS converter, Thus, the system is analyzed and PI compensation network is correctly designed. Finally, it is simulated using of matlab and simulation map is given, The results shows that the mathematical model is rational and design scheme is feasible.
