Design of Electronic Ballast for Short Arc Xenon Lamp With Interleaved Half Wave Rectifier
This paper presents an interleaved half wave rectifier circuit, which constitutes an electronic ballast with high open voltage gain and current doubler. It is suitable for applications in short arc xenon lamp needing high open circuit voltage and low operating voltage. By integrating interleaved half wave rectifier with LCC resonant circuit, the electronic ballast can provide a low arc sustaining current dc power source with low ripple and dimmable capability along with starting current suppression feature. Finally, a 25 A 500 W short arc xenon lamp electronic ballast is developed to possess full load efficiency as high as 91.32% along with dimming range falling between 7.6% and 100% and peak starting current being as low as 16 A.
