Abstract
The present invention relates to a single-stage dimmable electronic ballast for high intensity discharge (HID) lamps. The electronic ballasts consist of a high-frequency inverter, a load resonant tank, a high voltage ignition circuit and a dimming circuit. High power conversion efficiency is achieved by the proposed single-stage topology with zero-voltage-switching (ZVS) feature. A spread-frequency technique is used to eliminate the acoustic resonance phenomenon of HID lamps under high frequency operation. Wide dimming range can be accomplished by using the proposed dimming technique.
