Abstract
The output voltage of a flux controlled transformer is regulated by controlling the magnetic flux flow in the main core of the transformer. This regulation is achieved by a magnetic structure which includes a main core with primary and secondary coils thereon; shunt cores symmetrically situated about the main core; and leakage paths symmetrically positioned about the main core so as to interconnect the main and shunt cores. In one configuration the leakage paths include magnetic laminations which are positioned perpendicular to the magnetic laminations which form the main and shunt cores. In another configuration the magnetic laminations are arranged in a trapezoidal configuration.
