Abstract

Based on the background of battery charging system, in this paper, the small-signal equivalent circuit model of phase-shifted full-bridge ZVS DC/DC converter is established, then its transfer function is derived, and a single closed-loop voltage-mode controller is designed. In order to analyze anti-grid voltage disturbance capacity, transfer function of audio susceptibility is presented, and the anti-grid disturbance capacity in open-loop system and single closed-loop system is analyzed in theory and is verified by simulation respectively.
