A generalized predictive current control method based on two vectors for three-phase voltage source inverters

In this paper, a generalized predictive current control method based on two vector utilization in one sampling period are proposed for regulating load currents of three-phase voltage source inverters (VSIs) with small current errors and current ripples. In the proposed method, selecting two future voltage vectors and partitioning them in a future sampling period are determined by an optimization process, by considering all 49 possible combinations producible by two voltage vectors of the three-phase VSI.
