Abstract
Circuit arrangement having a free-running half-bridge inverter for operation of gas discharge lamps. A stop device is used to enable the drive to the half-bridge switches only during an on time. The oscillation frequency of the half-bridge inverter can be adjusted by the duration of the on time. This allows control of the lamp operating variables.
