摘　　要：传统三相永磁同步电机使用脉宽调制算法调节三相电压时会产生较大的共模电压,加速电机部件损坏,缩短电机使用寿命。为解决这一问题,基于三相四桥臂电机拓扑,设计了一种抑制共模电压的模型预测控制策略,仅采用部分电压矢量进行优化调制,保证较低转矩脉动的同时抑制共模电压。经仿真验证,与传统方法相比,该控制策略可以使电机共模电压减少1/2,并确保电机动稳态性能保持不变。Traditional three-phase permanent magnet synchronous motors using Pulse Width Modulation to control three-phase voltage will generate a large common mode voltage,accelerate motor component damage,and shorten motor service life.To address this issue,this paper proposes a model predictive control strategy based on the three-phase four-leg motor topology to suppress common-mode voltage.By using a partial voltage vector for optimal voltage modulation,it is possible to guarantee low torque ripple while suppressing common-mode voltage.Through simulation verification,compared with traditional methods,this control strategy can reduce the common-mode voltage of the motor by half and ensure that the motor's dynamic and steady-state performance remains unchanged.
