Development of Electronic Ballast for Automotive HID Lamp
자동차 헤드라이트용 전자식 안정기 개발
Abstract
An electronic ballast for driving automotive HID lamps is presented. The circuit topology is composed of a fly back converter, a Ful bridge inverter, and an igniter. A prototype was developed and tested on a 35W lamp with a 12V input voltage. To avoiding the acoustic resonance, the full bridge inverter is operated at 250Hz and provided a squared-wave voltage source to the lamp. The transient and steady state characteristics of the tested HID lamps are measured and analyzed.
