Abstract

This study compares sinusoidal PWM and SVPWM for v/f control of induction motor drive with three level inverter and under various modulation indices. It also suggests a proportional control-based neutral point controller for neutral point voltage balancing.When compared to the similar methodologies, the simulation results produced in the MATLAB/Simulink environment show that the proposed method is preferable.
