单片机控制的工频焊机节能控制器设计

Design of the Energy-save Controller for the Power Frequency Arc Welder Based on MCU Controlling

随着经济建设的发展,工频交流焊机和工频整流焊机的应用越来越广泛,但此类焊机负载持续率低,空载电压高,既存在安全隐患,又造成大量电能的浪费。本文依托单片机控制技术,对工频焊机的安全节能控制进行研究,并取得良好的控制效果。

With the developement of economy construction , the use of power frequency ac arc welder and rectifier arc welder is more and more extensive .But the duty cycle of them is small and the voltage without load is high.So it will endanger the life of welder and a lot of energy is wasted The safe and energy-save controller is studyed in this paper based on the monolithic microcomputer.It has been used and the effect is well.
