Synchronous Reluctance Motor Drive System Fed From Three-Phase Matrix Converter

Abstract

This article introduces three-phase synchronous reluctance motor (SynRM) drive system based on matrix converter. A SynRM is selected in this drive system due to its higher efficiency and better cooling compared to induction machines. In this drive system, matrix converter is used to control SynRM as there is no big DC link capacitor in this converter as in the traditional rectifier inverter. This reduces the repetitive maintenance of the drive system. Moreover, the AC input voltage is directly converted to the output side with the required amplitude and the required frequency without any reactive element. This converter is capable of producing an extensive range of output frequencies. Indirect space vector modulation is implemented to control the converter switches with field-oriented control technique. The drive system's performance is studied at various operating condition either in torque control mode and in speed control mode.
