The formula for calculating layer windingcapacitance is proposed by making the input impedance of the equivalent circuits equated and a method which can simplify the calculation processes is given.
The new model includes winding leakage, iron losses and distributed capacitance. It has more similarity to the actual model. At last this model is verified by simulation.
