Abstract

This paper presents a digital control strategy for Input-Parallel Output-Parallel (IPOP) DC/DC converters system. The IPOP system is based on two phase-shifted full-bridge (PS-FB) converters whose output current is not equally shared due to parameter differences of each module. The control objective is to obtain output current equally sharing. Small signal model is built to analyze the system stability. Effectiveness of the control strategy is verified by simulation and experiment results.
