Direct Torque Control of Three-Phase Induction Motor by Single- to Three-Phase Matrix Converter

摘要

This paper presents switching-table based direct torque control of three-phase induction motor using a single to three phase matrix converter. The voltage vectors of converter are divided into two groups and a novel switching table based on the vectors is proposed regarding the effects of motor speed and load on torque changes. The proposed system is a good choice for low power applications especially home appliances. Simulation results are provided to confirm the performance of proposed strategies.
