A GENERALIZED MATHEMATICAL MODEL OF THE TWO-LEVEL CASCADED INVERTERS FEEDING THE OPEN-END STATOR WINDING INDUCTION MACHINE

Abstract

In this the authors propose the supply of the open-end stator winding asynchronous machine by voltage converter to each input, these converters constituted by two or several 2-level cascaded inverters. A generalized mathematical model of the « n » levels inverters feeding the open-end stator winding induction machine is presented. An extended generalized PWM strategy is carried out to control the converter
