| 摘 要： | 用80C196MC单片机实现异步电机变频调速的正弦脉宽调制和电压空间矢量脉冲调制。从理论上分析了它们的异同点，最后在一台三相异步电动机上进行了试验验证。实验结果表明：SVPWM调制比SPWM调制时电压利用率高、电流谐波小、高频噪声低。

| Abstract: | This paper implements sine pulse width modulation(SPWM),space vector pulse width modulation(SVPWM)using singlechip,and achieves the purpose of variable-frequency adjusting-speed for induction motor.Firstly the paper analyze their similarities and differences,then the design scheme is tested on an three-phase asynchronous motor.The results show that the method of SVPWM has more efficient use of supply voltage,lower current harmonic,lower noise than the sine pulse width modulation. |
