全数字无速度传感器电流型变频调速系统

All-Digital No-speed-sensor Vector Control Current-inverter Control System

  • 摘要: 提出了基于无速度传感器矢量控制的电流型变频调速系统,并介绍了负载开路时,晶闸管保护的方法,电动机侧并联LC谐波滤波器的作用.

     

    Abstract: Deal with no-speed-sensor vector control current-inverter control, and the way of protect SCR when load ciruit open. The results showed that AC motor is filtered by LC filter.
