Performance Improvement Technique for Induction Motor Driven by a Matrix Converter under Abnormal Input Conditions
نویسندگان
چکیده
Matrix converter (MC) is an AC-AC power converter topology that directly converts energy from AC source to an AC load without using any energy storage components. Therefore, the disturbances in the input voltages can propagate onto the output side and degrade or even deteriorate the performance of motor load. This paper investigates the behavior of MC and its influence to the performance of induction motor under unbalanced input condition. A feed-forward compensation technique to eliminate the output voltage distortion of MC and ensure the proper operation of induction motor under unbalance is then proposed. Effectiveness and feasibility of the compensation method has been demonstrated through simulation results.
