A predictive direct power control strategy for three-level npc rectifier

In this paper, a predictive direct power control (P-DPC) strategy for a three level NPC rectifier under ideal grid voltage is proposed, discussed and applied. With the proposed P-DPC strategy, the control targets are the active power, the reactive power and the neutral potential voltage; neither hysteresis comparators nor switching table are needed; sinusoidal input current with low total harmonic distortion (THD), smooth regulation of both powers (active and reactive power), and neutral point voltage are achieved. Finally, by using Matlab/Simulink, the performance and effectiveness of the proposed P-DPC strategy is verified via simulation results.
