Reactance and Eddy Current Loss in Toroidal Transformatoric Devices-II

A metal layer may be required for various reasons between two windinglayers of toroidal transformers. The reactance flux, crossing such a metal layer, generates eddy currents in it. A semigraphical calculation of the resulting losses, presented in this paper, is based on a known formula for eddy current losses in steel laminates of a core and on the author's companion paper-Part I.₁ A numerical example explains the application.
