Abstract :
This paper proposes the predictive direct power control (P-DPC), a new control approach where the well-known direct power control (DPC) is combined with a predictive selection of a voltage-vectors sequence, obtaining both high transient dynamic and constant switching frequency. Two different P-DPC versions are developed based on two different types of voltage sequences: a two-vector one and a three-vector one. Simulation results of the three-vector sequence P-DPC are compared to standard voltage oriented control (VOC) strategies. Thanks to its high transient capability and its constant switching behaviour the P-DPC could become an interesting alternative of standard VOC techniques for grid-connected converters
