Abstract :
Nowadays simulation tools are widely used in the design process of power sources for arc and resistance welding. A modern inverter-type welding power source is a complex power electronic system, which is characterized by high switching frequency, fast dynamic response and a special load adapted process control. Although for an overall simulation on the system level simple semiconductor models may be sufficient, some relevant problems can only be solved on a circuit level simulation considering dynamic semiconductor models, driving circuits and parasitics. In this paper experiences with the practical parameterization and application of some recently introduced data sheet based models of diodes. MOSFETs and IGBT are described
