Multi-layer winding high-frequency transformer design method and device based on stray capacitance

The invention relates to a multi-layer winding high-frequency transformer design method based on stray capacitance, which comprises the following steps: acquiring specification parameters of a primary winding and a secondary winding in a multi-layer winding high-frequency transformer, voltages at two ends of the windings, magnetic core voltages and distributed capacitance at different positions, and inputting into a total stray capacitance calculation model; obtaining a total parasitic capacitance value of the multi-layer winding high-frequency transformer; and adjusting specification parameters of the primary winding and the secondary winding according to the total stray capacitance value until the total stray capacitance value meets a preset capacitance value range, obtaining the specification parameters of the current primary winding and secondary winding, and obtaining a target multi-layer winding high-frequency transformer. The total stray capacitance calculation model of the multi-layer winding high-fre
