基于高频交流升降压原理的双有源桥双向变换器
Dual-active-bridge Bidirectional DC/DC Converter Based on High-frequency AC Buck-Boost Theory
摘要
Abstract
In order to realize more optimized current stress of switches and soft switching in wider range,this paper proposed a unified high-frequency AC buck/boost (UHFBB) control strategy for dual active-bridge bidirectional converter (DAB-BDC).A multi-variable solving method was proposed and the calculation flow chart was given,which is the basis of the closed-loop control.The design method for variables of transformer turns ratio and the inductor value was shown.The current stress for switches was analyzed based on the optimized inductor value.The performance of the DAB-BDC was compared under UHFBB and DPS control strategy from the switch current stress,excavating the potential of the control variables and the range of soft switching.The analysis was verified by the experimental results from a 500W prototype.关键词
