1. A ferroresonant transformer adapted to be connected to a resonant capacitor, a primary power source that generates a primary power signal, and a secondary power source that generates a secondary power signal, the ferroresonant transformer comprising:

  • a core;

    a main shunt arranged relative to the core to define a primary side and a secondary side of the ferroresonant transformer;

    first windings arranged on the primary side of the ferroresonant transformer, where the first windings are operatively connected to the primary power source;

    second windings arranged on the secondary side of the ferroresonant transformer, where the second windings are operatively connected to the secondary power source; and

    third windings arranged on the secondary side of the ferroresonant transformer, where the third windings are operatively connected to the resonant capacitor;

    wherebywhen the primary signal is present on the first windings, a first output signal is present on at least a portion of the third windings; and

    when the secondary power is present on the second windings, a second output signal is present on at least a portion of the third windings.
