摘要
介绍了一种利用集成移相触发器KC05组成的移相触发电路,区别于传统的单结晶体管触发电路,该电路采用电压负反馈作为控制方式,主电路采用桥式半控整流的CO2送丝相控调速系统。该系统对输入电压范围要求宽,可适合多种送丝机的要求,具有结构简单、动态性能好、调速精度高等特点。经过实际应用,效果良好。
Different from the traditional single-junction transistor trigger circuit,this article describes a wire-feeding speed regulation system in CO2 welding,which used KC05 as a integrate phase shift trigger.This system adopts voltage negative feedback as the control method,and its main cireuit is half-bridge rectifier.The system with wide range input voltage is suitable for a variety of requirements and also has a simple structure,good dynamic performance and high precision.The practical application shows the system has good effect.
