Abstract :
In this paper, the start-up characteristics of automotive HID lamps with electronic ballast is investigated. In order to prevent the lamp from extinguish immediately after break-over, auxiliary current circuit is proposed to provide additional current to lamp. During warm-up or run-up phase, DC lighting period also is needed to light a discharge lamp more reliably at the starting time of the discharge lamp. Experiments have been carried out to verify the function of these two proposed solution.
