Evaluation of Direct Torque Control Using Space Vector Modulation for Electric Vehicle Applications

Abstract

This paper presents the results of an investigation into the suitability of a Direct Torque Control method for an electric vehicle application. For this investigation, a 2.2kW specially rewound induction motor driven using a three-level IGBT inverter switching at 10kHz was used. The control scheme used and the test system that has been developed are explained. Simulated and experimental results are presented. The control scheme is computationally complex, but is shown to have low current distortion, low torque ripple, and a fast torque response.
