This paper presents a new model predictive current control (MPCC) method in order to reduce common-mode voltage (CMV) for a three-phase voltage source inveter (VSI). By utilizing twenty-one vectors instead of eight vectors used in the conventional MPCC method,the proposed MPCC method can not only reduce the CMV but also improve load current performance. Simulation results are given to verify the effectiveness of the proposed MPCC method.
