The data acquisition process is an important step in the development of device models, and usually requires large amounts of time. Besides, since it is a process controlled by a scientist, it is subject to human errors. The automation of this process by a configurable system removes the human error factor and does not require full time attention from the scientist. These drawbacks are more evident...
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...
This paper presents an electronic ballast to operate HO fluorescent lamps with power ratings of 24 W, 39 W and 49 W. The proposed circuit detects the lamp type by its operation voltage and sets duty cycle of the power factor correction circuit to adequate the output power. Experimental results are shown to demonstrate the feasibility of the proposed solution.
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...
