Abstract
A ferroresonant transformer assembly, which is adapted to be connected to a primary power source, an inverter system, a resonant capacitor, and at least one load, comprises a core, a main shunt, and first, second, and third windings. The main shunt is arranged to define a primary side and a secondary side of the ferroresonant transformer. The first windings are arranged on the primary side of the ferroresonant transformer and are configured to be operatively connected to the primary power source. The second windings are arranged on the secondary side of the ferroresonant transformer and are configured to be operatively connected to the inverter system. The third windings arranged on the secondary side of the ferroresonant transformer and are configured to be selectively operatively connected to or disconnected from the resonant capacitor.
