18 ABSTRACT OF THE DISCLOSURE A transformer utilizing a rotating flux for saturating the entire core. The transformer uses a core configured such that a vector sum of the induction pro- duced by two windings in the core rotates through 360°. This is accomplished by arranging the component induction vectors to be perpendicular and the source voltages asso- ciated with each of the component induction vectors to be 90° out of phase. If the inductions are of equal magni- tude and the vector sum is sufficient to saturate the core, rotation of the vector sum saturates the entire core and the transformer experiences a very low or nearly negligible hysteresis losses. Various topological confi- gurations for the core, including a toroid, are described. The transformer windings can be arranged for single, two-phase, three-phase, or multi-phase operation.
