A four-level open-end winding induction motor drive (OEWIMD) is obtained when an induction motor with open windings is fed from either side with two two-level 3-Ph voltage-source inverters (VSIs) with unequal dc-link voltages, which are in the ratio of 2:1. This drive principally suffers from two problems namely: the circulation of zero sequence current in motor phases and overcharging of the lower...
In this paper, a SVPWM for an indirect matrix converter (IMC) with dual output inverter has been proposed to eliminate the common-mode voltage (CMV). The presented converter is a combination of the conventional rectifier stage and a dual inverter stage for feeding open-end winding load. The principles of selecting suitable active vectors and zero vectors and then properly arranging the switching sequence...
A modified space vector pulse width modulation (SVPWM) strategy based on vector space decomposition and its equivalent dual three-phase SVPWM realization are proposed in this paper, which is suitable for two-level six-phase voltage inverter fed asymmetrical dual stator induction machines (DSIMs). The DSIM is composed of two sets of symmetrical three-phase stator windings spatially shifted by 30 electrical...
