The 6th IMI Colloquium   Date：15 February 2012 (Wed) 17:00-18:00           (16:30-17:00 tea time at common room) Place：Lecture Room L-1 (3F, IMI, Kyushu University) Speaker：Kenji Miyata (Hitachi Researh Lab., Hitachi, Ltd.)   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.   IMI Colloquium Report
