Modulation Techniques applied to Medium Voltage Variable Speed Drives - SHE and OPP

Abstract

This paper presents an analysis of the modulation techniques selective harmonic elimination (SHE) and optimum pulse pattern (OPP) applicable for medium voltage motor drive converters. The document reviews some basic concepts of these techniques and presents a comparison of simulation and experimental results with optimum patterns, selective harmonics, suitable applications and scenarios for the use of filters.
