An Efficient Method for Solving Nonlinear Time-Periodic Eddy-Current Problems

Solution of nonlinear problems of time-periodic eddy currents in ferromagnetic media is performed by combining the time-harmonic analysis with a polarization fixed point procedure. The proposed method always yields stable results, even when the characteristic B-H is strongly nonlinear, and has a superior computational efficiency with respect to the direct transient solution method and to the harmonic balance method
