Abstract :
In view of the large signal characteristics of the dynamic process of arc welding, a nonlinear model of a control system for a welding inverter has been put forward and computer simulation is conducted. From the comparison between the simulation and experiments, it is proved the model is correct, and the method is a useful approach for analysis of arc welding power supply
