Abstract :
An accurate, analytical method is proposed for calculating the lead and winding high-frequency resistance of complex transformer constructions. High-frequency resistance is derived from the resulting matrix system equations, common to the leads and windings. The effect of eddy currents in the leads is confirmed by theoretical results. The high-frequency resistances of three winding arrangements are compared, and a winding geometry that reduces winding high-frequency resistance is derived
