Abstract

This paper investigates the performance analysis of various Multicarrier Pulse Width Modulation strategies with Sinusoidal reference for single phase seven level diode clamped Z-source inverter designed with two intermediate Z-source networks connected between the input source and inverter circuit. The diode clamped Z-source based MLI strategy enhances the fundamental output voltage and reduces the Total Harmonic Distortion (THD). Performance factors such as %THD, Vrms where measured and CF, DF of output voltage are calculated for different modulation indices 0. 8-1. The results are compared. The simulation results indicate that the use of Z-Source in DCMLI boost 60% of the total output voltage. PODPWM strategy provides low THD and COPWM strategy is found to perform better since it provides relatively higher fundamental RMS output voltage.
