Abstract

This paper presents six reduced switch count ac drive systems. These configurations have been conceived to operate with a four-phase and a three-phase or with a four-phase and a two-phase induction machines in a series-connected scheme. The overall control of the drive system is presented, including the pulse width modulation techniques. The proposed two-motor drive systems are seen as a potentially feasible industrial solution for applications that demand one high-power and one low-power machine. Experimental results are presented.
