A ballast (10) for powering at least one gas discharge lamp (70) having heatable filaments (72,74) includes an inverter (200), a resonant output circuit (400) coupled between inverter (200) and lamp (70), and a filament heating and ignition control circuit (600) coupled to inverter (20...
Once this conduction is connected the current consumption to sustain this conduction and the illumination becomes minimal. Electrical ballasts are used just to “kick” this initial current and then control the supply of the current by offering increased impedance once the ignition is completed. Use ...

Gas discharge lamps such as fluorescent lamps require ballast in order to properly start and maintain lamp ignition to produce adequate light from the lamp. Ballast may be of electromagnetic, electronic or solid state types. With newer lamps, electronic ballast have been required in order to provid...
