Comparison between Fast Steady-State Analysis Methods for Time-Periodic Nonlinear Magnetic Field Problems

摘要

This paper investigates the effectiveness of various methods to accelerate the convergence to a steady state in time-periodic electromagnetic field problems. We introduce the time-periodic explicit error correction (TP-EEC) method considering both dc and linearly-varying error components. The advantages and disadvantages of the TP-EEC method and the time differential correction (TDC) method are discussed from the standpoints of computational costs and the application scope.
