摘要电流型隔离DC-DC变换器具有电流脉动小的优点,有利于延长储能系统锂电池的使用寿命;同时,减小开关损耗是提高功率变换效率的关键技术之一。因此该文讨论利用电流型推挽隔离DC-DC变换器开关管的寄生电容进行谐振,满足开关管的软开关条件。首先分析变换器的增益特性和工作模态;其次基于变换器的等效电路模型,详细分析推挽型隔离DC-DC变换器的软开关瞬态过程,推导出变换器全部开关管软开关条件的参量表达式;最后通过仿真和实验结果验证了软开关条件的正确性。

Abstract：The current source isolated (CSI) DC-DC converter has the advantage of low current ripple, and it is beneficial to the service life of the lithium battery of the energy storage system. At the same time, reducing the switching loss is one of the key technologies to improve the power conversion efficiency. Therefore, this paper discusses the method of using the parasitic capacitance of the push-pull CSI DC-DC converter switch tube to perform resonance to meet the soft-switching conditions of the switch tube. Firstly, the gain characteristics and operating mode of the converter are analyzed. Secondly, based on the converter's equivalent circuit model, the soft-switching transient process of the push-pull CSI DC-DC converter is analyzed in detail, and the parametric expressions of the soft-switching conditions of all switches of the converter are derived. Finally, the simulation and experimental results verify the correctness of the soft-switching conditions.

Key words： DC-DC converter soft-switching push-pull isolation
