Abstract
Abstract This invention is directed to an integrated ferroresonant stabilizer having a regulated constant voltage output and in which the secondary windings, of foil interleaved with a dielectric film, provide both inductance and capacitance. A high degree of electrical efficiency is achieved, together with low weight and volume. No external capacitance is required.
