Optimal Control Strategy for Bidirectional DC-DC Converter under V2G Application Scenarios
充电站内的双向充电堆采用引入三电平桥臂的三电平双有源全桥3L-DAB(three-level dual active bridge)DC-DC变换器,通过增加控制自由度来增强系统调节的灵活性.当采用传统移相CPS(conventional phase shift)控制时,3L-DAB电流应力较大,损耗增加,系统效率降低.针对此问题,提出一种适用于双向充电堆中DC-DC变换器的电流应力最小优化控制策略.首先建立移相控制3L-DAB的数学模型,分析电…查看全部>>
A three-level dual active bridge(3L-DAB) DC-DC converter with the introduction of 3L legs is applied to the bidirectional charging stack in a charging station,so that the system's regulating flexibility can be enhanced by adding another control degree of freedom.When the conventional phase shift(CPS) control is adopted,the current stress of the 3L-DAB converter is relatively large,which increases the loss and thus reduces the system efficiency.To address thi…查看全部>>
