Equivalent circuit of the multiwinding powerful toroidal welding transformer

Abstract

The paper proposes an original equivalent circuit of the multiwinding transformer based on the classical theory of transformers and the introduction of a new parameter — the mutual inductance on leakage fluxes. The results of the calculation of currents and losses in the windings of a powerful toroidal transformer on the base of the original equivalent circuit of the multiwinding transformer are confirmed experimentally.
