| Abstract |
An electronic ballast for driving automotive HID lamps is presented. The circuit topology is composed of a fly back converter, a half bridge inverter, and ignitor using voltage doubler. A prototype was developed and tested on a 35W lamp with a 12V input voltage. To avoiding acoustic resonance, the half bridge inverter is operated at 400Hz 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. |
