Abstract :
In this paper, the small-signal model of a current mode control full-bridge phase-shifted ZVS PWM converter is derived based on the small-signal model of the converter. Through the transformation of the current mode small-signal model into the respective transfer function model, a simplified close loop current mode small-signal transfer function of the converter is obtained. By using the derived small-signal model, it is possible to design the compensation network of the converter in the frequency domain
