摘　　要：本文针对在线式UPS中具体的实用性需求,提出了采用双向变换器代替DC-DC升压变换器和电池充电器的新方案。文章详细分析了双向全桥软开关DC-DC变换器的基本工作原理,并对相关元器件进行了设计闸述了实现软开关的方案,并进行了实验验证。Basing on the practical requirements of on-line UPS, a new scheme adopting bi-directional converter is proposed to replace the DC-DC boost converter and the battery charger. This paper analyzes the principle of bi directional soft--switching DC-DC full-bridged converter in detail, and gives the design principle of the related components. The scheme of realizing soft-switching is also Provided. Finally, the experimental setup is built and the results verify the validity of the proposed approach.
