Abstract
This application discloses a power electronic transformer wherein each phase includes a plurality of power conversion modules. Each power conversion module includes a rectifier AC/DC circuit, a direct current bus capacitor, and a direct current-direct current DC/DC circuit. In each power conversion module, an output end of the AC/DC circuit is connected to an input end of the DC/DC circuit; the direct current bus capacitor is connected in parallel to the output end of the AC/DC circuit; and input ends of all the AC/DC circuits are connected in series, and output ends of all the DC/DC circuits are connected in parallel. The power electronic transformer includes a relatively small quantity of power conversion modules, thereby reducing occupied space and costs.
