This paper proposes a deadbeat finite set model predictive current control based on discrete space vector modulation (DSVM) in order
to achieve robust characteristics from the grid impedance variation while guaranteeing high performance of output current waveforms
and a fixed switching frequency. The proposed DSVM strategy enables to obtain a large number of virtual voltage vectors without
complex initialization process or lookup table, which are the drawbacks of the conventional DSVM strategies. A deadbeat technique
was adopted to minimize the number of candidate voltage vectors considered in the cost function in order to avoid the high
computational burden caused by considering all voltage vectors. The simulation and experimental results were presented to verify the
effectiveness and performance of the proposed method using a two-level grid-connected voltage source inverter.
