Abstract :
This paper proposes an electronic ballast utilizing piezoelectric transformers for fluorescent lamps. The electronic ballast composed of new-type piezoelectric transformers and a half-bridge parallel-resonant inverter was implemented. It enables a fluorescent lamp to be turned on stably, and achieves an efficiency over 80% in steady state
