Abstract

A method to detect the occurrence of the acoustic resonance based on lamp electrical parameters has been proposed. Extensive experiments are conducted on 70 W metal halide lamps from different manufacturers and a lamp acoustic resonance detection method based on ΔR/R variation is developed. A new topology for a smart ballast which selects the operating frequency for stable operation based on real time measurements is proposed
