Automatic lamp detection technique for self-oscillating fluorescent lamp electronic ballasts

This paper presents a self-oscillating electronic ballast to operate T5 HO fluorescent lamps with power ratings of 24 W, 39 W and 49 W. The proposed circuit detects the lamp type by measuring the lamp voltage through a control circuit which changes the power factor correction circuit duty cycle to a...

Zusammenfassung:This paper presents a self-oscillating electronic ballast to operate T5 HO fluorescent lamps with power ratings of 24 W, 39 W and 49 W. The proposed circuit detects the lamp type by measuring the lamp voltage through a control circuit which changes the power factor correction circuit duty cycle to adequate the output power. Experimental results are shown to demonstrate the feasibility of the proposed solution.
