Model predictive control of a direct three-to-seven phase matrix converter

This paper proposes a model predictive control technique for a direct multi-phase matrix converter with three phase input and seven phase output. The proposed predictive control strategy simultaneously controls the active and reactive power in addition to the source and load current. The proper switching states are predicted according to the optimization algorithm of the cost function. The cost function is developed to control the input power factor along with seven phase load current tracking. The model predictive algorithm is presented in the paper, and the viability of the proposed solution is proved using analytical, simulation and experimental approach.
