Abstract
A ferroresonant transformer is adapted to be connected to a primary power source, an inverter system, and a resonant capacitor. The ferroresonant transformer comprises a core, a main shunt arranged to define a primary side and a secondary side of the ferroresonant transformer, first windings arranged on the primary side of the ferroresonant transformer, second windings arranged on the secondary side of the ferroresonant transformer, and third windings arranged on the secondary side of the ferroresonant transformer. The first windings are operatively connected to the primary power source.
