摘要
分析了异步电机三角形接法采用空间矢量脉宽调制(SVPWM)技术时,基本电压空间矢量的大小与相位,分析结果表明:电机在Y接与△接时,逆变器相同的开关状态所形成的电压空间矢量的大小及相位均不相同。在此基础上给出了△接法时扇区的划分及扇区号的确定方法。
The phase and amplitude of the space vector PWM accord with different switch states was presented. The results showed that there are some differences between Y and △ about the space vector PWM on the asynchronous motor. Finally, the sectors were divided in a new method provided.
