Modelling, simulation and analysis on various front-end rectifiers schemes for PMSM motor drives

Abstract

This paper presents different types of rectifier schemes such as 12, 18, 24 and 36 for grid utility interface with low power variable frequency drives (VFD). To demonstrate Ithd at a Point of Common Coupling (PCC), system level modelsare developed for different rectifier systems. The configurations are simulated and implemented using MATLAB-Simulink. The study involves comparison of different rectifier schemes with respectiveIEEE-519(2014) standard for various short circuit ratios (SCR).A detailed harmonic analysis of different configurations is made and complete results are presented. A comprehensive study on different rectifier schemes is made and their overall performance is studied and discussed.
