Abstract
This invention relates to methods of providing uninterruptible, regulated, single phase power to a critical single phase load when such power is derived from two of the phases of a polyphase power source. This invention describes a dual primary ferroresonant transformer which provides regulated and isolated voltage to a single phase critical load, when powered by a plurality of phases from a polyphase power source, and whereby a loss of electrical power to either a first or a second primary does not disturb the single phase power output voltage.
