Abstract

This paper deals with the Predictive Direct Power Control of MV-grid-connected two-level and three-level NPC converters. The well-known direct power control is combined with a predictive selection of a voltage-vectors sequence, obtaining both high transient dynamic and constant switching frequency on high-power converters. The initial Predictive Direct Power Control proposal explored only the basic formulation based on simple vector-sequences applied to two-level converters. Later on, the same approach was extended to the family of three-level NPC converters, including the predictive direct control of neural voltage. In the same way, an advanced hybrid Predictive Direct Power Control was presented, providing only simulated data. The work presented in this paper provides experimental results of the hybrid Predictive Direct Power Control applied to two-level and three-level NPC converters. These results show that the P-DPC approach is an attractive solution to MV grid-connected applications.
