摘要/Abstract

摘要： 本文提出了一种新型的双有源桥（Dual Active Bridge, DAB）LCC谐振双向DC-DC变换器，将LCC谐振槽应用到传统的DAB双向DC-DC变换器中。本文分析了正向传输功率时，该变换器具有的变压器原边开关管零电压开关（zero voltage switching, ZVS）和副边整流二极管零电流开关（zero current switching, ZCS）的优点。同时，还分析了反向功率传输时的buck工作模式。仿真和实验结果证明本文所提出的变换器可以实现功率双向传输并实现开关管的ZVS和ZCS开关。

Abstract: A novel dual active bridge (DBA) bidirectional DC-DC converter with LCC resonant net was proposed. The converter was composed of LCC resonant net and traditional bidirectional DC-DC circuit with zero voltage switching (ZVS) operation of the primary side switches and zero current switching (ZCS) operation of the rectifier diodes in forward power transition. This paper analyzed the buck operation mode in the reverse direction. The simulation and experimental results illustrates that the proposed topology can realize the power transition in both directions and the switches can be turned ON and OFF in ZVS and ZCS.
