Abstract

In this paper, decoupled space vector based PWM techniques are proposed for vector controlled open-end winding induction motor drive. The proposed decoupled PWM techniques reduce the ripples in both stator current as well as in torque, unlike conventional PWM techniques. All the proposed decoupled SVPWM techniques are obtained by phase shifting the one inverter reference sinusoids by 1800 with respect to the other inverter reference sinusoids. A commonmode voltage is identified in the open-end winding induction motor drive. The proposed PWM techniques also reduce the common-mode voltage by great extent. To demonstrate the proposed work, several simulation studies have been carried out using MATLAB/SIMULINK and the corresponding results are reported and compared.
