The special hysteresis characteristics of a laminated core (LC) under AC-DC Hybrid magnetization are obtained by test. The field-circuit coupled time-periodic finite-element method (TPFEM) combined with the fixed-point method is used to calculate the exciting current and magnetic field of the LC based on the DC-biased magnetizing curve. The behavior of LC with no-load and different loads under AC-DC...
The harmonic balance finite element method (HBFEM) is combined with the fixed-point technique to calculate the steady-state magnetic field in a laminated core model (LCM). The magnetic intensity is divided into linear and nonlinear parts in the form of harmonics. The hysteresis model based on the consuming function is taken into account in the harmonic computation. The magnetic field and magnetizing...
