Bidirectional half-bridge three-level DCDC conversion circuit

The invention discloses a bidirectional half-bridge three-level DCDC conversion circuit and relates to the technical field of automatic control and power electronics. The bidirectional half-bridge three-level DCDC conversion circuit includes a transformer, circuits on the two sides of the transformer are divided into a primary circuit and a secondary circuit, the two ends of the transformer are respectively connected in series with a first energy storage inductor and a second energy storage inductor, the voltage peak value borne by each power switch device of a bidirectional half-bridge three-level DC/DC converter is only half that of a two-level rectifier, the voltage stress of a power switch tube is reduced, the problem that the switching devices are generally not high enough in withstand voltage is well solved, the switching loss of the bidirectional DC/DC converter can be effectively reduced, the working efficiency of the converter is improved, the power density and the dynamic performance of the converte
