The utilization of three-level T-type (3L T-type) inverters in finite set-model predictive control (FS-MPC) of grid-connected systems

yielded good performance in terms of current ripples and total harmonic distortions. To further improve the system’s performance,

discrete space vector modulation (DSVM) was utilized to synthesize a higher number of virtual voltage vectors. A deadbeat control

(DBC) method was used to alleviate the computational burden and provide the optimum voltage vector selection. However, 3L

inverters are known to suffer from voltage deviation, owing to the imbalance of the neutral-point voltage. We have proposed a

simplified control strategy for balancing the neutral point in the FS-MPC with DSVM and DBC of gridconnected systems, not requiring

a weighting factor or additional cost function calculation. The effectiveness of the proposed method was validated using simulation

and experiment results. Our experimental results show that the execution time of the proposed algorithm was significantly reduced,

while its current quality performance was not affected.
