Computational Speed Improvement of Reluctance Network Analysis Combined with Play Model

This paper proposes a method to improve the solution convergence of the reluctance network analysis model incorporating the play model by decomposing the DC hysteresis characteristics into linear and nonlinear terms and applying the play model only to the latter. In this way, it is possible to increase the width of a time step by converging the solution in nonlinear iterative calculation and, as a result, to shorten calculation time by reducing the number of time steps.
