Abstract

This paper presents a feedforward fluorescent lamp power regulation method for self-oscillating electronic ballast for different line voltages. The proposed method consists in maintaining the lamp power regulated through the feedforward switching frequency variation using the output resonant filter feature and self-oscillating gate driver circuit. Experimental results demonstrate the feasibility of the proposed solution that allows regulating the lamp power in a wide input voltage range (110 to 220 V_rms ) with an error of up to 12%.
