Abstract

A circuit is provided for providing a regulated d.c. output of a substantially high output current magnitude from an unregulated single or polyphase a.c. input source. Regulation is provided by a single feedback circuit interacting with a plurality of ferroresonant transformers connected in parallel to a single phase source, singly on each phase or a polyphase source, or interconnected in the known Scott T connection on a three phase source. Regulation is accomplished with thyristor switches which are synchronized with the input phase of each transformer.
