摘　　要：介绍了空间电压矢量脉宽调制(SVPWM)变频的基本原理及其实现方法。详细分析了电压矢量与磁链矢量之间的内在联系。利用MATLAB/SIMUL INK实现了对该系统的仿真。最后以TMS320LF2407为控制核心进行了硬件实现。结果表明,该系统具有直流电压利用率高,开关损耗小,转矩脉动小的优点。This paper starts with the introduction of the theory and the realization of space vector PWM. The relationship between space vector and flux vector is elaborated. The simulation testing is carried out through MATLAB/SIMULINK. Based on DSP controller TMS320LF2407, a hardware system is introduced at last. The experimental result presents that the system has achieved a higher capability, with the virtue of and full use of DC voltage, low switching loss and pulsatile torsion.
