Abstract
The modified harmonic balance finite element method was applied to investigate the DC biased problem in the saturated electromagnetic devices. The electromagnetic field was solved by the block Gauss-Seidel algorithm combined with the relaxation iterative method. The DC bias effects on magnetizing current and magnetic induction was analyzed by means of harmonic solution in multi-frequency domain. The computation is more efficient than the time-domain FEM and harmonic analysis can be achieved.
