Abstract-A low-cost high-efficiency high power-density electronic ballast for 35 W automotive high intensity discharge (HID) lamps is presented along with the results of theoretical computations and experimental tests. The ballast circuits is based on a 100 kHz resonant inverter, a half-wave rectifier and a 400 Hz operated square-wave inverter. The converter operates at zero turn on losses, nearly zero turn off losses, and at a reduced electromagnetic interference level. The ballast circuit is designed to prevent inappropriate operations due to the acoustic resonances. The lamp voltage waveform has limited and no dc component contributing to a long operating life of the lamp.A breadboard of the electronic ballast was designed and experimentally tested on a 35 W lamp, for a dc input voltage ranging from 9 V to 16 V.The electronic ballast performs all the features required to turn-on, warm-up and drive at the steady state a 35 W HID lamp and operates at a maximum steady state efficiency =84%.
