ABSTRACT:
AC voltage is applied to a resonant unit provided with an inductor and a capacitor AC current is supplied to a discharge tube connected to one of the inductor and the capacitor according to the switching operation of the two power semiconductor elements connected in a bridge manner. The resonant unit and first and second voltage drop units are connected in series between I/O terminals of the bridge and the voltages of the first and the second voltage drop units are applied as signals of opposite phases to control terminals of the two power semiconductor elements.
