基于三端口变换器的单相双向AC-DC变换器：减少功率处理级数并提高整体效率

Single-phase bidirectional ac–dc converters based on a three-port converter (TPC) are proposed for energy storage applications. Three power interfacing ports, i.e., a dc-bus port, a dc input port, and an ac port, are provided by the proposed converter. A battery, whose voltage is lower than the peak amplitude of the ac voltage, is connected to the dc input port of the TPC, with which energy exchan...
