<p>Several embodiments of a variable flux transformer are described which are quite simple in design and yet provide a greater range of adjustment of the output emf than prior art arrangements. Each transformer includes a core of a magnetic fluxconductive material having three legs extending from a common cross bar, which legs terminate at free ends which are spaced from one another. A primary electrical coil is interactively associated with one of the legs, and a secondary electrical coil is interactively associated with another leg. The third leg is used to complete a magnetic flux path from the primary coil leg bypassing the secondary coil leg. A magnetic flux control switch which is also of magnetic flux-conductive material is positioned at the free ends of the legs for appropriacely bridging the spacings therebetween to complete only those low reluctance flow paths between such legs desired at any given time. 1.</p> |
