Induction motor drive system for low-power applications

Abstract

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