Abstract
This paper presents a comprehensive SPICE model of a power inductor including winding losses, eddy current losses within a soft magnetic ferrite material and hysteresis losses as well as the selfresonance. With an adaption of the wellknown Steinmetz's equation for hysteresis losses, nonsinusoidal waveforms of hardswitching topologies such as DC/DC converters or PFC stages are taken into account. The smallsignal impedance of the power inductor is modeled on basis of smallsignal measurements that are adapted to an equivalent circuit by an algorithm. Outstanding advantages of the model are the simple generation out of data sheet parameters and a single impedance measurement as well as a good accuracy.
