Abstract
A three-phase electronic ballast used to drive a plurality of fluorescent lamps and to keep the current flowing through the fluorescent lamps is described. The electronic ballast includes a three-phase power driving circuit, three transformers and three resonant circuits. The primary sides of the three transformers are formed to a delta connection, and are used to receive the three-phase voltage from the three-phase power driving circuit. The secondary sides of the three transformers are formed to a Y connection, and are used to provide stable three phase output voltages. The output voltage of each phase is filtered by a resonant circuit for providing a sinusoidal voltage to at least one lamp load.
