ABSTRACT:
An operating circuit for a gas discharge lamp includes a rectifier to be connected to an AC power line for generating positive and negative DC voltages, a first inverter connected to the rectifier for converting the DC voltages into a first substantially square wave AC signal, a series resonator for connecting the first inverter with a first lamp electrode, and a second inverter connected to the rectifier for converting the DC voltages into a second substantially square wave AC signal. The second inverter is to be connected to a second lamp electrode. The first and second substantially square wave AC signals have substantially equal fundamental frequencies and are out of phase.
