[Abstract]:In view of the requirement of high efficiency welding to increase welding current to improve production efficiency, In this paper, two inverters are used in parallel to realize high power output of pulsed MIG welding inverter. Digital signal processor (TMS320LF2407A) is used to construct parallel digital control system of high power pulsed MIG welding based on DSP. The rich peripheral equipment of DSP is used. Resources and excellent control performance, Two inverters are controlled by a single DSP, which ensures the parallel output of the welding power source. The results show that the designed parallel high power pulse MIG welding inverter can realize high current and high efficiency welding, and the welding performance is stable. The weld is beautiful in shape.
