Abstract
Digital control system based on mixed-signal FPGA for pulse MIG welding power source is designed to solve the deficiencies in control system based on analogous control technology, such as poor reliability, poor flexibility and unsatisfactory process effect and to realize the welding arc length stable control.This paper proposes one kind of arc length control strategy based on adjusting the base current time, the design of the control system hardware circuit and realizes the pulse current waveform output.The welding experiment shows that the pulse MIG welding power source based on mixed-signal FPGA has advantages,such as high-speed dynamic response, high reliability, stable welding arc length control and high welding quality.关键词
