摘要
提出一种基于单片机的PWM转DAC方式,实现对通用变频器的自动控制,包括启停控制、频率调节等,通过在SX-608D实训平台上的变频器实际运行,取得了很好的控制效果。本设计具有成本低廉,控制小巧等优点,通过简单改进,如增加光耦隔离等,可用以实际工业控制。
This paper presents a PWM based on microcomputer to DAC mode, to realize the automatic control of the general frequency converter, including start and stop control, frequency regulation, through the frequency converter in SX-608D training platform on the actual operation, has achieved a good control effect. This design has the advantages of low cost, control cabinet and so on. Through simple improvement, such as increasing the optocoupler isolation,it is available to the actual industrial control.
