Abstract
The present invention relates to an electronic ballast for fluorescent lighting fixture, comprising a rectifier circuit with filter, a flyback converter circuit, a half-bridge type switching circuit and a control circuit used to control power and switch process. The power control method adopted by the flyback converter circuit, in addition to be capable of working on different input voltage or its variation, providing stable power and lighting and reducng aging effect, it also achieves high power factor. When combined with the half-bridge switching circuit to switch control process, provides a traditional ballast tube warm-up mode, but also a control function of light adjustment. Thereby, the electronic ballast is characterized in that the circuit structure as a whole is simple and needs no complicated resonance control circuit and theory, and provides advantages of high efficiency, low cost and extended lifetime of tube, good warm-up function, light adjustment, and power factor correction.
