Current harmonics mitigation of model predictive controlled inverter by zero state modulation

This study aims to mitigate the problem of current ripple associated with model predictive control of inverter. The suggested modified model predictive control strategy operates the inverter in two states per switching interval: an active state and a zero state. A modified voltage model-based prediction equations derived to determine the optimum active state and its duty ratio according to the cost function. Simulation results show that the modified model predictive control reduces the current harmonics by up to 25% compared to the basic model predictive control.
