Abstract

This paper presents the comparative study of various Multicarrier Pulse Width Modulation techniques with Sinusoidal reference for single phase seven level cascaded Z-source inverter designed with three intermediate Z-source networks connected between the input source inverter circuit. The cascaded Z-source based MLI technique enhances the fundamental output voltage and reduces the Total Harmonic Distortion (THD). Performance factors such as %THD,Vrms and CF of output voltage are measured for different modulation indices 0. 6-1. The results are compared. The simulation results indicate that the use of Z-Source in CMLI boost 50% of the total output voltage. APOD PWM technique provides low THD and COPWM provides high DC bus utilization.
