Abstract
Apparatus for conversion of alternating current at a first frequency to alternating current at a second (lower) frequency in a power control circuit by means of progressive variation of magnetic flux in associated magnetic paths. Control is achieved by progressive saturation or domain rotation for selected portions of the magnetic paths to yield a uniformly controllable permeance within the magnetic paths. Feedback circuits provide a means for external control of the output in combination with a reference source.
