Abstract

The Jiles-Atherton (J-A) model is used to simulate the magnetization process in a gapped magnetic core. A test platform for investigating the magnetic properties of a gapped core is designed and constructed. The hysteresis curves of an amorphous alloy core are measured for different gap lengths. Simulated hysteresis curves based on the original and inverse J-A models are obtained and are compared with the measured curves. The simulation result based on the original J-A model is better than that based on the inverse J-A model. The applicability of a modified J-A model to gapped cores is analyzed. The influence of gap length on inductance is analyzed from the perspective of the magnetic circuit. The inductance is calculated based on the J-A model, and the results indicate that the J-A model has high accuracy in this application.
