摘　　要：传统的SPWM法比较适合模拟电路实现,不适应现代电源的发展趋势。电压空间矢量脉宽调制(SVPWM)技术和传统的SPWM法相比,它具有电压利用率高、输出电压畸变小、谐波含量低、控制方法简单、且易于实现数字化等优点,因此本文在基于SVPWM技术的基础上,对三相变频电源的控制系统进行了研究。The traditional SPWM method is suitable for analog circuit rather than the development trend of modern power. Voltage space vector PWM （SVPWM） control technology is an PWM control technique, which not only has a DC high utilization rate, a low output voltage distortion rate and a low harmonic content, but also the control method is simple, and it＇s easy to implement digitally compared to the traditional SPWM method. SVPWM technique. The control system of the three-phase variable- frequency power supply is researched based on SVPWM technique.
