Open-end winding induction machine supplied by two flying capacitor multilevel inverters

In this paper the authors propose the open-end winding induction machine supplied by two multilevel inverters with flying-capacitor, two PWM strategies, phase-shifting PWM and phase-disposition-band are presented. A generalized mathematical model of the ≪ n ≫ levels inverters feeding the open-end stator winding induction machine is presented. An extended generalized multilevel PWM strategy is carried out to control the inverter.
