摘要
设计一种无级调速的风机。通过改变控制信号PWM脉冲宽度来改变IGBT导通与截止时间的比,调节风机两端的输出电压,实现对风机转速的控制,能够较好地满足对风机转速的实际要求。
This paper designed a variable speed fans,which used the width of PWM pulse signal to change the ratio between the IGBT conduction and cutoff time,then adjusted both ends of the output voltage to control the fan speed.It is easy to meet the practical requirements of clients and plant sites.
