Reduced Switch Count Dual-Winding AC Drive Systems

This paper proposes four reduced switch count dual-winding ac motor drive topologies. Two topologies consist of a five-leg converter feeding a dual-winding induction machine. The other topologies are conceived to be used with four-leg converters. The control strategies for the motor drive systems are investigated. The main characteristics of the motor drive systems are also presented. Simulated and experimental results are presented to demonstrate the feasibility of the proposed solutions
