  • Abstract
    This paper is a theoretical study of the magnetizing current components. Three conditions were investigated: 1. Sinusoidal voltage supply. 2. Sinusoidal voltage with dc bias. 3. Sinusoidal voltage with sinusoidal bias. The magnetizing curve is approximated with the equation. The analysis leads to closed expressions that enable the quantitative evaluation of effects dependent on the core geometry and physical constants of the active materials. H = asinh(bB). The analysis leads to closed expressions that enable the quantitative evaluation of effects dependent on the core geometry and physical constants of the active materials.
