Abstract
This paper presents a novel approach of space vector pulse width modulation techniques (SVPWM) used for two and three level Z Source Inverter (ZSI). The ZSI is a single stage converter and capable of doing buck and boost operation. Boost facility is obtained by adding extra state named as shoot through state and additionally DC bus utilization can be improved by proper placing of shoot through states in all the sectors. The voltage unbalance is reduced by proper use of pivot vectors. It has been observed that the proposed SVPWM offers better results in comparison to standard sine PWM techniques. Simulated results are presented for validating the analysis.
