A Single-Stage High-Power-Factor Dimmable Electronic Ballast with Asymmetrical Pulse-Width-Modulation for Fluorescent Lamps

, 2000
A single-stage high-power-factor electronic ballast is designed for fluorescent lamps with dimming capability. The circuit configuration is originated from the integration of the half-bridge resonant inverter and the buck-boost converter.
