ABSTRACT:
A ferro-resonant, voltage-regulating transformer. The transformer has a primary winding formed about a portion of each leg in each of two spaced, juxtaposed cores. A regulated output voltage is produced at a resonant circuit formed by a capacitor and a secondary winding around another leg of the first core. The flux variations in the two cores are continuously out of phase with each other. As the primary voltage changes the magnitude of the total flux in the system, the flux in the second core can vary in magnitude and phase thereby to maintain the flux in the first core at a constant level. Thus, the output voltage at the resonant circuit is substantially constant.
