准方波调制DC-DC变换器的双模式运行以提升全工况效率

Extending the use of dc–dc converters, such as the dual active bridge (DAB) to high voltage applications, will require voltage sharing among series-connected power devices. Initial solutions used snubber capacitors to limit voltage rise and balance the turn-off voltage. However, this mechanism is not viable at low currents, which leads to high capacitor discharge currents. The quasi-square-wave mo...
