Abstract :
The DC biased problem of the Epstein Frame-like core model is investigated by using the Harmonic Balance Finite Element Method (HBFEM). It considers coupling between the electric circuit and the magnetic field. The magnetizing current and its harmonic components can be calculated directly in the harmonic domain. Comparing the calculated results with the experimental data shows consistency. The DC bias effect on the harmonic components of the exciting current is analyzed directly with the distribution of the magnetic flux visually observed through the harmonic solutions.
