Abstract:The soft-switching conditions and the power transmission characteristics of bi- directional full-bridge DC-DC converter based on dual-phase-shifting control are analyzed.The dual-phase-shifting control strategy with the minimum backflow power under ZVS soft-switching conditions are proposed. Based on the averaged modeling method, a small-signal model with the dual-phase-shifting control of the bi-directional full-bridge DC-DC converter is presented. At last,based on an experimental prototype, the effectiveness of the models and proposed control strategy are validated by experiments in both transient and steady state operations, and experimental results also verify the effectiveness of the proposed control strategy to improve the efficiency of the converter.
