Abstract
Disclosed is an improved shunt core transformer in which a primary winding drive generates a varying magnetic flux field around a transformer core which field thereby induces the plate voltage induces a voltage in both a first secondary and second secondary coil. The second secondary coil however is made of a ferrous material and thereby functions to shunt a portion of the flux generated directly from the central leg to the outer legs of the core bypassing the first secondary coil and thereby providing the known protections of a shunt core transformer.
