Abstract

The present paper deals with the modeling in high frequency of AC machines windings, when the coils are subjected to fast slopes of MLI voltage. The purpose of this study is twofold: firstly, to develop a network of the electrical circuit, and secondly, to effectuate a behavioral analysis. The different elements of this network will be identified by Finite Element Calculations thanks to COMSOL MULTIPHYSIC software, and a behavioral analysis of this network is simulated by MATLAB SIMULINK. This analysis confirms the occurrence of voltage spikes in the first few turns of the coil. Finally, an improvement to face these surges is proposed, consisting in modification of the coupling of partial coils of the winding. Simulated and experimental results are matching well and highlight the merits of the present approach.
