<p>A principal winding is wound around two cores made of soft magnetic material. The principal winding has N turns. Wound around only one of the two cores is a magnetizing winding. A decoupling amplifier of gain v1 energizes the magnetizing winding via the amplifier output, and the amplifier has an input across which is applied the voltage across the principal winding. The magnetizing winding has v1.N turns. If the principal winding and the magnetizing winding have the same winding direction, then the gain of the decoupling amplifier is chosen positive. If the principal winding and the magnetizing winding have opposite winding directions, then the gain of the decoupling amplifier is chosen negative.</p> |
