Abstract

In this paper, the improved modeling of the linear compressor system is researched considering the magnetic nonlinearity. The strategy for modeling the linear compressor considering the magnetic nonlinearity is conducted in two steps. Frist, nonlinear inductance values of the linear compressor are calculated by electromagnetic field analysis using the Finite Element Method. Secondly, the modeling of controller is performed by analysis of the loss factor of the linear compressor system. The power calculation of nonlinear modeling of the linear compressor system is verified through experiments.
