Abstract The gyrator-capacitor model of the magnetic components has shown it's superiority in simulation for the electric and magnetic information integrity, convenience in the modeling and the mixed magnetic and electronic system simulation. This paper proposes an improved gyrator-capacitor core model, with a nonlinear resistor to simulate the hysteresis characteristic, with a nonlinear capacitor to simulate the core saturation. The model equation is presented in this paper as well as the parameter determination and optimization method. The simulation B-H curve comparing with that in datasheet proves the validity of the modeling method. The proposed simulation model is used in the system simulation of a 400kHz Buck converter and a multi-output converter with the magnetic amplifier regulator. The simulation results are consistent with the experimental results or the principle analysis, and verify the effectiveness of the proposed core model.
