Research of single phase-shift close-loop control for bi-directional full-bridge DC-DC converter

In view of problem of low efficiency of bi-directional full-bridge DC-DC converter based on traditional single phase-shift control, the paper proposed a design scheme of bi-directional full-bridge DC-DC converter based on single phase-shift close-loop control. It analyzed steady characteristics of the bi-directional full-bridge DC-DC converter and detailedly introduced modeling implementation of the bi-directional full-bridge DC-DC converter based on single phase-shift close-loop control. The simulation and experiment results show that the converter has high efficiency and low loss.
