Permeance based modeling of magnetic hysteresis with inclusion of eddy current effect

Abstract

Magnetic hysteresis together with eddy current effects are typically present in metal based core materials and contribute significantly to the nonlinearity and power loss of the magnetic components operating in power electronic converters. In order to investigate their influence on the system's behavior in time domain, model which is accurate and simple enough to be integrated into circuit simulation environment, is desired. This work proposes a modeling's approach using permeance-capacitance based magnetic circuit, which combines the hysteresis and eddy current effect of the magnetic components in system-level time domain simulation.
