Abstract
After the modulation algorithm of the two-stage matrix converter rectifier stage and the control strategy of inverter direct torque were deeply analyzed, a control strategy that two-stage matrix converter drived induction motor direct torque was proposed in the paper. The thought of zero current switching was adopted as the commutation method, namely, zero current switching of rectifier stage could be insured by inserting short periods of zero switching states around the points at which the rectifier stage commuted. The advantages of two-stage matrix converter and the direct torque control were combined in this strategy to make power factor adjustable and be of good dynamic and static performance. The simulation results prove the feasibility and effectiveness of the control strategy and indicate that the control strategy has perfect speed modulation as the DC speed control system.关键词
