Title:Fast analysis method of time-periodic nonlinear fields
 
Abstract:
Two types of methods will be presented for fast analysis of time- periodic nonlinear fields. One is TP-EEC method using the explicit error correction method, and the other is TDC method using a time differential technique. The principle of these methods will be shown together with numerical analysis results in a simple 2nd order simultaneous differential equation. Furthermore will be shown a generalization of simplified three-phase TP-EEC method which is the simplified TP-EEC method expanded to three-phase alternating-current system. Numerical analysis results of steady-state nonlinear magnetic field will be shown in a static apparatus and a rotational machine using the above correction methods.
