Parasitic Capacitance Modeling of Inductors Without Using the Floating Voltage Potential of Core

The analytical modeling of parasitic capacitances in inductors is commonly based on the energy-conservation law. Yet, order to calculate equivalent inductors, floating voltage potential magnetic core required be preknown all previous methods. This letter proposes an method for calculating with low-resistivity cores, which does not require any prior knowledge potential. proposed can extended transformers as well multiterminal devices. experimental results verify effectiveness method.
