Multi-rating Electronic Ballast for Fluorescent Lamps based on Operating Frequency Determination

抄録

This paper presents an electronic ballast system with lamp rating detection capability. From the experimentally obtained operating frequency of the lamps, a possibility weight is constructed to help facilitate the lamp classification. The proposed detection algorithm employs a multi-step lamp power regulation algorithm where decision making is based on the sensed frequency and the possibility weight. Simulation and experimental results show that the proposed detection method can successfully detect the targeted lamp power rating and deliver the desired power to the lamp.
