Research of Equivalent Circuit Model of Magnetic Component in Magnetic Integration Technology

Equivalent circuit models of magnetic component are summarized and a new model is proposed, where the structure of magnetic component is reflected and the circuit analysis is carried out flexibly. The relationship figures of four kinds of equivalent models of magnetic component are gained with this model, and the identity of these four kinds of models is confirmed. To simplify the computing method of magnetism saturation, a magnetism switch component is designed in gyrator-capacitor model. The simulation result indicates the feasibility and accuracy of this method. Furthermore, the difficulty of calculating parameters in developing equivalent circuit can be solved by the aid of electro-magnetic field analysis software.
