Direct Torque Control (DTC) is a preferred method for its fast torque response and easy implementation in induction motor (IM) applications. However varying switching frequency and current harmonics are the drawbacks of the method. There are many industrial applications already using DTC. In this study, a novel switching table is proposed to reduce current harmonics based on torque-flux plane that can be applied to current motor drives with software modification, rather than a hardware advancement. The study is illustrated with Simulink model and motor output results. Keywords: Direct Torque Control, Torque-Flux Plane, Total Harmonic Distortion, Vector Selection Table.
