摘　　要：随着新能源车辆市场占有率的增加,电驱系统性能受到广大学者和汽车行业从业人员的关注。正弦脉宽调制和空间矢量脉宽调制作为两种常用的车用电机控制方案,其涉及的调制度与电压利用率指标影响着电驱总成系统性能,提高调制度进而提升逆变器电压利用率,可以在母线电压一定的前提下,提高电驱系统转矩与功率。本文对SPWM和SVPWM两种控制方案下的调制度和电压利用率概念进行阐述,并通过理论分析及仿真手段加以验证说明,为后续提升系统性能提供理论基础。With the increase of market share of new energy vehicles,the performance of electric drive system has attracted the attention of scholars and automobile industry practitioners.Sinusoidal Pulse Width Modulation(SPWM)and Space Vector PWM(SVPWM)are two commonly used control schemes for motor vehicles.The regulating system and voltage utilization index involved affect the performance of the electric drive assembly system.Improving the regulating system can improve the voltage utilization of the inverter,which can improve the torque and power of the electric drive system under the premise of a certain bus voltage.In this paper,the concepts of regulation and voltage utilization under SPWM and SVPWM control schemes were described,and verified by theoretical analysis and simulation.This provides a theoretical basis for improving system performance.
