Abstract :
This paper deals with the control improvement of a middle-frequency resistance spot welding system. This is achieved by a combined closed-loop control of the welding current and closed-loop control of the iron core saturation level. The proposed control assures a very short rise time of the welding current and the best possible utilization of the transformer iron core.
