Single-stage dual-mode three-port power electronic converter

The invention relates to a single-stage dual-mode three-port power electronic converter, and belongs to the field of electronic devices. The single-stage dual-mode three-port power electronic converter comprises a direct-current side filter capacitor, four switching devices, two alternating-current side filter inductors, two alternating-current side filter capacitors and three output ports. The single-stage dual-mode three-port power electronic converter is simple in topology and low in cost, one path of direct current and one path of alternating current of different voltage levels can be output at the same time under the condition that only one basic topology is used, or three paths of direct current electric energy of different voltage levels can be output at the same time, the modulation method is simple and easy to implement, and the problems that an existing multi-port power electronic converter is complex in topology, high in cost and low in power density are solved. 本发明涉及一种单级式双模式三端口电力电子变换器，属于电子器件领域。单级式
