Round wire type high-frequency transformer design method and device considering actual turn length

The invention relates to the technical field of power electronics and power transmission, in particular to a round wire type high-frequency transformer design method and device considering the actual turn length. According to the method, the instantaneous power consumed in the pth layer winding and the integral area of the Poynting vector of the outer side surface or the inner side surface of the pth layer winding are obtained by calculating the difference value of the integral areas of the Poynting vectors of the outer side surface and the inner side surface of the pth layer winding; the porosity is the product of the porosity, the power flow density at the outer side surface or the inner side surface of the pth layer of winding, the total height of the winding and the outer perimeter or the inner perimeter of the pth layer of winding; the method for calculating the instantaneous power through the poynting vector makes it possible to consider the actual turn length, and compared with a previous method using
