摘要
研究了开关型送丝电源 ,采用由PWM调速、光电测速的PID自动调节系统 ,实现了稳定等速送丝、调速范围宽、送丝速度采用数字指示并可预调。该送丝电源成本低 ,体积小 ,重量轻 ,性价比高 ,是一种值得推广的电路。
A new type wire feeder power supply—high frequence switch power,using a PID automatic adjusting system by PWM regulating speed circuit and light-electricity measuring speed circuit,has been developed.The experimental results show that the wire feed rate which regulated range is wide,and could be digital display and regulated beforehand,is stable.The cost of the power supply is low,the volume is small,the weight is light,and the ratio of property to price high.It should be a kind of circuit worth spreading and applying.
