Transformers of high frequency resistance spot welding systems are considered. The equivalent circuit of a three-winding transformer, which is obtained by replacing it with two two-winding transformers, is used. It is shown that the magnetic coupling factor for the leakage fluxes of these two-winding transformers influences on the output current. The study of the transformers includes both 2D eddy-current FEA analysis for estimation the leakage impedance and the circuit simulation, which gives the output current. The results are used to design economical welding transformers. The calculation results are confirmed experimentally.

PL

Zaprojektowano transformator do wsokoczestotliwościowego punktowego zgrzewania. Przeprowadzono analizę rozkładu prądów wiroychw celu uwzględnienia impedancji upływowej oraz zaproponowano schemat zastępczy transformatora trzy-uzwojeniowego otrzymanego przez zastąpienie dwóch transformatorów dwu-uzwojeniowych.
