中文摘要:由于传统的正弦波脉宽调制(SPWM :Sinusoidal PWM)技术直流母线电压利用率低，谐波成分高等，针对这一问题介绍瞬时空间磁链矢量圆轨迹法(SVPWM: Space Vector PWM)技术。首先对SVPWM原理进行了详细的分析，在此基础上确定SVPWM算法实现的基本流程，并将SVPWM技术应用于三相永磁同步电机控制系统中，在SIMULINK中建立整个系统的仿真模型，仿真结果表明SVPWM控制方法能够实现等效正弦电压的输入，为SVPWM控制策略在永磁同步电机调速系统中的应用提供了一定的理论依据。

Simulation Study on SVPWM Principle and Inverter Technology

Abstract:Aiming at the low utilization rate of the traditional sine pulse width modulation technology of DC bus voltage and high harmonic components, etc, this paper introduced a space vector pulse width modulation (SVPWM) technology. Firstly, the principles of SVPWM technology was detailed, the basic process of SVPWM algorithm was determined, the SVPWM technology was applied to the control system of three-phase PMSM, and the simulation model of the whole system was built in SIMULINK. The simulation results show that the SVPWM control method can achieve equivalent sinusoidal voltage input. It provides a theoretical basis for the application of SVPWM control strategy in permanent magnet synchronous motor speed control system.
