Indirect torque control of induction motor based on two-stage matrix converter

Two-stage matrix converter, which can achieve all the traditional matrix converter features, has relatively small number of switching devices, greatly simplified clamp circuit, reliable commutation, simple modulation strategy and easy to be implemented. After a brief analysis of the two-stage matrix converter topology, this paper gives a detailed deduction of indirect torque control algorithm of induction motor. Finally, with the compensation of intermediate DC voltage modulation strategy, system simulation model is built up based on Matlab/Simulink. The simulation results show the correctness and effectiveness of the algorithm.
