This paper is based on the design and analysis of Total Harmonic Distortion(THD) and power factor for Compact Fluorescent Lamp. In the proposed electronic ballast Buck Boost converter operates in the continuous conduction mode, which provides a constant DC voltage to drive the lamp.By choosing the switching frequency more than the resonant frequency the zero voltage switching is achieved in res...

In this paper, a new method is proposed to avoid acoustic-resonance-related instabilities in metal halide lamps when operated with a high-frequency electronic ballast. Angle modulation of the inverter switching pattern has been used as a vehicle to randomize lamp driving frequency and to limit lamp power spectrum below the instability threshold. The optimal modulating pattern is obtained by stu...
