ABSTRACT:
A discrete type starter for HID lamps uses a ferrite core pulse transformer whose secondary is connected in series with the lamp across a ballast output winding. The primary is formed by mounting one or more sidacs and a resistor astride the core loop and interconnecting them by cladding on the board to make two or three turns around the core. The primary is connected across a capacitor which is connected in series with an impedance across the ballast output winding.
