ELECTRONIC BALLAST OF ARC LAMPS FOR SMOOTHER DRIVEN PERFORMANCE AND MODIFIED STRUCTURE OF ARC LAMP SOURCE

摘要

An electronic ballast for arc lighting sources for balanced power driving, arc lighting source, and power control system, making possible longer working life by regulating the functioning of arc lighting sources, as well as more economical operation adaptable to the magnitude of the local line voltage. An electronic ballast for arc lighting sources (1) has a line rectifier unit (2), phase correction block (3), direct current voltage storage (4), DC/DC converter unit, DC/ AC inverter unit (6) and choke (7), connectable to the electrodes (18) of the source (1). A microcontroller (8) with independent supply unit (11) is connected to the DC/DC converter unit. A source (1) has a third electrode (19), situated on the wall of the high pressure gas space (17), and said electrode (19) is connected to a voltage generator (12) of high voltage The microcontroller (8) has power line interface (10) suitable for long distance control.
