abstract
2017 IEEE. This paper proposes a novel optimized control strategy of quasi-Z source indirect matrix converter (QZS-IMC) for induction motor drives. The QZS-IMC provides boost function to overcome the output voltage limit of the traditional matrix converter, and achieves a voltage gain over 0.866. This paper proposes an indirect field oriented control (IFOC) technique based closed loop speed control of an induction motor fed by a QZS-IMC. By selecting the best optimized shoot-through duty ratio (D), modulation index (mi;) of the rectification stage and modulation index (mo) of the inversion stage, the solution ensures effective control and stable system. The simulation results are conducted to validate the proposed control strategy.
