Method and device for designing round wire type winding high-frequency transformer based on direct-current resistor

The invention relates to the technical field of power electronics and power transmission, in particular to a design method and device for a round wire type winding high-frequency transformer based on direct-current resistance. According to the design method of the round wire type winding high-frequency transformer based on the direct-current resistance, the direct-current resistance of the primary winding is obtained through the direct-current resistance calculation model, specification parameters are adjusted according to the resistance value of the direct-current resistance, and the transformer meeting the circuit requirement is obtained. The direct current resistance calculation model is obtained by enabling a round wire type winding to be equivalent to a rectangular wire winding with the same cross section area, calculating the instantaneous power by using a poynting vector, and calculating the direct current resistance through strict logic derivation. And finally, the direct-current resistance is calcula
