Description
Summary:Dynamic behavior is of great importance for a welding power supply, but has not been investigated adequately. In view of the large signal characteristics of the dynamic process of arc welding, a nonlinear model of the control system for the 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 and design of an arc welding inverter.
