ABSTRACT:
An oscillating flux transformer for transforming relatively large blocks of electrical power at power frequencies in direct accordance with the turn ratio of toroidal primary and secondary windings. The transformer includes a core-coil assembly having a poloidal winding in addition to primary and secondary toroidal windings, with the poloidal and toroidal windings being disposed on a magnetic core which is in the form of a closed loop or torus. Direct current in the poloidal winding establishes an equilibrium position of a saturation induction phasor. The AC flux produced by the toroidal primary winding combines vectorially with the DC flux to cause the induction phasor to oscillate about the equilibrium position, with an angular excursion responsive to the magnitude of the voltage applied to the toroidal primary winding.
