Predictive control method for load current of single-phase voltage source inverters

This paper proposes a model predictive current control (MPCC) method utilizing two output voltages with variable application durations in one sampling period, to control output currents of single-phase voltage source inverters (VSIs). In the proposed method, application durations of the two voltages as well as selection of two output voltages used in the future sampling period are determined by an optimization process, to minimize current error inside the future sampling period and to eliminate current error at the end of the future sampling instant.
