Abstract

Apparatus for control of direct current by means of systematic switching and progressive variation of magnetic flux in associated magnetic paths. Subdivision of the input DC power between two transformer devices permits transformation by controlled electromagnetic induction into stabilized outputs which may be recombined into continuous DC power at controlled voltage or current levels.
