Comparison of three‐phase three‐level voltage source inverter with intermediate dc–dc boost converter and quasi‐Z‐source inverter

Abstract

This study compares a three‐phase three‐level voltage source inverter with an intermediate dc–dc boost converter and a quasi‐Z‐source inverter in terms of passive elements values and dimensions, semiconductor stresses, and overall efficiency. A comparative analysis was conducted with relative parameters to evaluate converter parameters for any application. The equations obtained were confirmed by simulation and experimental setup. Field of application has been discussed.
