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.

本文提出了一种简化的模型预测电流控制（MPCC）策略，以消除由单个DC供电的双五相电压源逆变器（VSI）供电的开放式负载的共模电压（CMV）并降低电流谐波来源。为了消除CMV并减少电流谐波，已为拟议的MPCC策略开发了21个虚拟电压矢量作为输入控制集。在每个采样间隔中，根据所需电压矢量的位置信息，在21个虚拟电压矢量中确定了五个虚拟电压矢量。然后通过新的成本函数对它们进行评估，以选择最佳的电压矢量。因此，由于省略了当前的预测计算，因此显着减少了计算负担，并且成本函数计算减少到了5。
