Bidirectional high-voltage DC/DC topological structure of multi-coil single-phase intermediate-frequency square wave transformer

The invention discloses a bidirectional high-voltage DC/DC topological structure of a multi-coil single-phase intermediate-frequency square wave transformer. The bidirectional high-voltage DC/DC topological structure comprises a controller and a filter inductor, wherein the controller is of a multilevel half-bridge control unit serial structure, each half bridge control unit consists of two parallel branch circuits, and a middle point of the branch circuits is respectively connected with a coil of transformer windings. Each coil of the transformer windings is independently led to the controller, the each half bridge control unit of each group of coils of the same winding of a transformer is connected towards polarity in series to form winding control topologies, and two groups of winding control topologies are separated by the filter inductor and then connected towards polarity in series. The bidirectional high-voltage DC/DC topological structure can effectively improve the time change rates of voltage and cu
