摘要
变频控制技术很好地实现了交流电机的无级调速,在运行中有诸多技术优势,是传统控制技术所无法相比的,在水泵的变频调速运行中取得了显著的节电效益。主要介绍了变频调速控制技术的控制结构及电机线电压PWM波形分析等。
The frequency control technique, which is used to realize the infini tive stage transmission of AC motor very well, possesses much technical superior ity in the operation, and the traditional control techniques can't compare with it, by using it the obvious power-saving benefit has been obtained in water pum p's frequency control operation. This paper mainly introduces the control struct ure of frequency control technique and PWM waveform analysis of motor's line-vo ltage, etc.
