Induction motor drive system for low power applications

Abstract

This paper investigates the utilization of three configurations of induction motor drives to implement low cost systems for low power applications. The static power converter side is implemented by using a single-phase rectifier cascaded with a four-switch inverter (FSI). Three types of induction machines are supplied with the static power converter. In the first scheme, a standard three-phase induction machine is employed. In the second, the load is a three-phase induction machine where only two windings are used. In the third, a standard two-phase induction machine is employed. Simulation and experimental results are provided to illustrate the operation of the systems.
