Abstract

This paper presents various level shifted multi carrier PWM techniques such as PD,POD and APOD for a cascaded H-Bridge multi level inverter fed induction motor drives. The performance analysis of these modulation strategies are analyzed by apply for five level, seven level, nine level and eleven level inverter. The performance analysis of cascaded H-Bridge interms of line voltage, stator current, speed, torque and total harmonic distortion. The results are depicting that PD-PWM is more effective among the three proposed PWM techniques. The proposed technique has been simulated using MATLAB/SIMULINK software. These Level shifted PWM techniques can be applied to N-level cascaded Inverter also.
