Abstract: The working situation of the flyback transformer in automotive HID electronic ballast was analyzed. Based on the analysis, a practical design method was presented to achieve the appropriate parameters of the flyback transformer. The selection of magnetic core as well as the design of turns, air gap and winding was discussed in detail. The experimental result is given and has proved the design is correct.
Key words: transformer; high intensity discharge （HID）; electronic ballast; flyback converter
