Modulated Model Predictive Control for 3TSMC

In this digest, the modulated model predictive control (MMPC) method for the three-phase third-harmonic injection two-stage matrix converter (3TSMC) is proposed, where the inverter and the current injection link are independently modulated. The sinusoidal input currents are achieved by the predictive control of the current injection link, simultaneously the output currents are obtained by the predictive control of the inverter. The proposed MMPC method guarantees good system performance at low switching frequency, and it eliminates the weight factor used to balance the input and output performance. The simulation results verify the correctness of the proposed method.
