Abstract

In this paper, a finite-control-set model predictive control (FCS-MPC) base on virtual voltage vectors is proposed for three-phase three-level (3P-3L) T-type voltage source converters (VSCs). Different from traditional method, a set of 51 virtual voltage vectors (VVs) is used in this method. Thus, the performance of the VSC is improved and the harmonic of output voltage decreased significantly. At the same time, the VVs used in this method have no effect on the neutral point (NP) voltage of VSCs. Furthermore, the multi-objective cost function including the NP voltage balance term in the traditional method is optimized, and the design process is simplified. In order to prove the effectiveness and validity of the proposed FCS-MPC and show its advantages over typical strategy, simulation results are presented.
