Cost-effective mitigation measures concerning conducted emission of resistance welding inverters

Resulting from the constantly increasing number of electrical and electronic appliances in both commercial and private spheres and the ongoing process of standardisation in the field of electromagnetic compatibility, there is a growing consciousness regarding possible electromagnetic interference problems of appliances. In the case of resistance welding equipment, special attention is paid to the occurring electromagnetic emissions because of the high rated-power parameters and the intermittent operation of these devices. Different noise mitigation measures, considering the special characteristics of the generation and propagation of disturbances in the case of resistance welding inverters are discussed in this paper.
