摘　　要：针对三相电压源逆变器驱动电机系统存在较高共模电压的问题,提出一种虚拟矢量模型预测电流控制方法,以非零矢量合成虚拟矢量构成有限控制矢量集代替传统的脉冲宽度调制方法,抑制系统共模电压。提出的控制方法可以在抑制共模电压的同时提高负载电流性能。仿真和实验结果验证了方法的有效性。In order to solve the problem of high common mode voltage in three-phase voltage source inverter drive motor system, avirtual vector model predictive current control method is proposed. Instead of the traditional pulse width modulation method, thesynthetic vector synthesized by the nonzero vector suppresses the commonmode voltage.The traditional pulsewidthmodulation （PWM）method is replaced by a set of finite control vectors composed of non-zero virtual vectors to suppress the systemcommonmode voltage.The proposed control method can not only suppress the common-mode voltage but also improve the load current performance.Simulation and experimental results verify the effectiveness of themethod.
