双向全桥DC-DC变换器的回流功率特性分析
Reflow Power Characteristic Analysis of Bidirectional Full-bridge DC-DC Converter
摘要
Abstract
An phase-shifting control method with asymmetric duty ratio was proposed. The proposed control method could extend the transmission power adjustment range and reduce the reflow power of bidirectional full-bridge DC-DC converter. The working principle of the traditional single phase shift control and the proposed control method was analyzed,and the modal analysis of the proposed control method was carried out and the steady state mathematical model was established. The reflow power under both the traditional single phase-shifting control mode and the proposed control mode were compared and analyzed. The reflow power and current stress under the proposed control mode were relatively smaller and the transmission power adjustment range was expanded. Finally,the simulation results show that the asymmetric duty ratio phase shift control method can reduce the return power of bidirectional full-bridge DC-DC converter.关键词
