摘要
针对基于传统单移相控制的双向全桥DC-DC变换器存在效率低的问题,提出了一种基于单移相闭环控制的双向全桥DC-DC变换器设计方案;分析了双向全桥DC-DC变换器稳态特性,详细介绍了基于单移相闭环控制的双向全桥DC-DC变换器的建模实现。仿真与实验结果表明,基于单移相闭环控制的双向全桥DC-DC变换器效率高、损耗小。
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.
