摘要
采用双绕组接线、并用三相整流式调节器对其中性端进行PWM电压调节的三相异步电动机,能够在内补偿电容器的配合下,对转速与无功电流进行简易的双重调节。
Three-phase adjustable rectifier was applied to conduct the PWM voltage-control at the neutral end in the 3-phase asynchronous motor equipped with dou-ble-winding connection. If it was cooperated with the inner compensation capacitor, the simplified double-regulation on both rotating speed and idle current would be performed.
