Modelling of nonlinear inductor exhibiting hysteresis loops and its application to the single phase parallel inverters

Abstract

A modelling of magnetodynamic fields taking into account dynamic hysteresis loops was previously proposed for predicting three-dimensional magnetodynamic fields in electromagnetic devices [1]. This method is now applied to construct the lumped circuit model for nonlinear inductor exhibiting dynamic hysteresis loops. The lumped circuit model of nonlinear inductor is introduced into the simulation model of single phase paralell inverter, whose various characteristics are calculated and compared with experimental measurements. Good agreement is obtained.
