| Abstract: | In this paper, a kind of microcontroller-based electronic ballast for 35W automotive metal halide lamps is designed. The frequency conversion technique is adopted to realize quick start-up of metal halide lamps. High-voltage ignition circuit can be charged directly by peak output voltage of single-end flyback converter, eliminating the use of special ignition winding of traditional high-frequency transformer and hence reducing the size of component. The test results show that the electronic ballast is stable in performance with higher efficiency, meeting the illumination requirements for automotive headlights. |
