摘　　要：为了实现三半桥双向DC/DC变换器的零电压导通和关断,进一步提高变换器的性能,本文探讨了三半桥拓扑双向DC/DC变换器的软开关条件。通过理论分析和仿真验证,研究了影响三半桥双向DC/DC变换器的软开关条件的因素。结果表明,三半桥双向DC-DC变换器的软开关条件与其控制变量有关。In order to achieve the zero voltage open and close of triple half bridge bi-directional DC/DC converter,advancer the capability of power switch.The paper probe into soft switching conditions of triple half bridge bi-directional DC/DC converter.By analyze in theory and simulation validate,study the influence factor of the soft switching conditions of triple half bridge bi-directional DC/DC converter,the result indicate the soft switching conditions of triple half bridge bi-directional DC/DC converter is connect with its controlling variable.
