Abstract
A circuit for powering gas discharge lamps includes a power factor correction inductor coupled to a source of rectified, pulsating AC power. An energy storage circuit is connected to the power factor correction inductor, and a switch is coupled to a junction between the power factor correction inductor and the energy storage circuit. A resonant circuit couples the energy storage circuit to the gas discharge lamps.
