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...
This paper presents electronic ballast with dimming capability supplying a 32 W fluorescent lamp. The electronic ballast is a self-oscillating driving circuit and an additional circuit responsible to dimming the fluorescent lamp using a lighting dependent resistor. This luminous sensor measures the luminous flux level and set the lamp power through the voltage gain variation of the resonant filter...
