Abstract
This paper presents a simplified model-predictive current control (MPCC) strategy to eliminate the common mode voltage (CMV) and reduce current harmonics for a dual five-phase voltage source inverter (VSI)-fed open-end load supplied by a single DC source. To eliminate CMV and reduce the current harmonics, 21 virtual voltage vectors were developed as an input control set for the proposed MPCC strategy. In each sampling interval, among the 21 virtual voltage vectors, five virtual voltage vectors were determined according to the position information of the desired voltage vector. Then they were evaluated by a new cost function to choose the best voltage vector. Therefore, the computational burden is significantly reduced since the current prediction calculations are omitted, and the cost function calculations are reduced to 5. The validity of the proposed strategy has been verified by simulation and experimental results.
