ABSTRACT:
A transformer with a primary and a secondary core. The primary core is rectangular in shape with guide slots on the inside in the center of opposite legs and windings wound in opposition on the other two sides. The secondary core is rectangular in shape consisting of two V' shaped parts. A power end and a bypass end. The two legs of the secondary power core are shaped into a closed V' and the two legs of the secondary bypass core are shaped into an open V' to allow the legs of the bypass and power core halves to mesh. These two half cores are separated by a diamagnetic strip and bonded together with a low magnetic bonding agent. The power end of the secondary core contains the secondary windings. The complete secondary core is then inserted at a right angle through the guide slots in the primary core. As the secondary core is moved back and forth through the primary core, the ratio of the amount of ferromagnetic material in the bypass end and the power end in contact with the primary core changes and therefore changes the magnetic flux density in the power end of the secondary core thus altering power through the secondary windings.
