空间矢量脉宽调制（Space Vector Pulse Width Modulation,SVPWM）是控制交流异步电动机的一种常用控制方式。与脉宽调制（Pulse Width Modulation,PWM）技术相比,SVPWM技术用于交流调速系统不仅能提高电压利用率,而且具有转矩脉动小、噪声低等优点。本文在分析SVPWM基本原理的基础上,对基于TMS320LF2407A型DSP（Digital Signal Processor）产生SVPWM波形的硬件和软件实现方法进行比较,并用Matlab/Simulink软件对SVPWM调制波形进行了仿真实验,仿真结果验证了本文所提算法的正确性和有效性。

Space vector pulse width modulation（SVPWM）is a popular method to control the AC asynchronous motor.Compared with the pulse width modulation（PWM）method,the SVPWM can not only improve the efficiency in the utilization of voltage in an AC speed regulation system,but also have several advantages such as less torque ripple and lower noise.This paper analyses the basic principles of SVPWM,introduces and compares the hardware-and software-based methods to realize SVPWM waveforms based on DSP,and simulates SVPWM modulation waveforms using Matlab/Simulink.The simulation results show the correctness and effectiveness of the proposed algorithm.
