A New Alternate Fixed-Bias Inverter SVPWM Scheme for Open-end Winding Induction Motor Drive

Abstract

This paper proposes a new space-vector based Pulse Width Modulation (PWM) scheme for an open-end winding induction motor drive. This PWM scheme requires two isolated power supplies and uses instantaneous phase reference voltages. The circuit configuration requires two isolated power supplies for the dual inverter fed open end winding induction motor drive. By exploiting the rich switching redundancy that is offered by the circuit configuration, all the active states are used in clamping the inverters. The proposed scheme is simulated using MATLAB/Simulink platform and the simulated results are validated using dSPACE experimentation
