A power electronic transformer structure includes: a support, a high-frequency transformer, a base, high-voltage side modules, and a low-voltage side module. The high-voltage side modules are respectively located at the front, top, and back of the support; the low-voltage side module is located at the bottom of the support; the high-frequency transformer is located at the middle of the support.

Power electronic transformer structure

A high-frequency transformer includes: an iron core, primary windings and secondary windings, wherein the iron core is of an integrated equilateral triangle structure, the primary windings and the secondary windings are uniformly wound around three sides of the iron core, and the primary windings and/or the secondary windings are symmetrically distributed on the three sides.

High-frequency transformer

Disclosed in embodiments of the present invention are a control method and device for an alternating-current and direct-current conversion circuit, and a computer storage medium. The alternating-current and direct-current conversion circuit comprises a first commutation unit, a second commutation unit, and a coupling unit. By obtaining voltage information and current information of the alternating-current and direct-current conversion circuit, a controllable device of the first commutation unit can be controlled to be turned on in delay or turned off in advance; and the second commutation unit is controlled to work in a controllable rectification state or a controllable inversion state or an uncontrollable rectification state.
