三相移调制双有源桥变换器的解析闭式ZVS边界

A dual active bridge (DAB) is an isolated dc–dc converter that supports bidirectional power flow and hence finds a wide range of applications. To achieve high efficiency and power density, zero voltage switching (ZVS) is needed in all power devices. The magnitude of the current at the time of switching in a half-bridge leg must be more than a minimum value set by mosfet characteristics, dc bus vol...
