∗ Corresponding author Abstract -This exploratory study examined the possibility of driving a fluorescent lamp at high frequency with no serially connected passive elements. The proposed driver is a full bridge stage controlled by the phase shifted PWM scheme. Current feedback was used to stabilize the average of the rectified lamp current to a set value. The experimental results of this resear...

This paper presents electronic ballast with dimming capability supplying a 32 W fluorescent lamp. The electronic ballast is a self-oscillating driving circuit with an additional circuit responsible for dimming the fluorescent lamp based on a signal from a lighting dependent resistor. This luminous sensor measures the luminous flux level and set the lamp power by the voltage gain variation of th...

LAMP-based platform for SARS-CoV-2 RNA detection incorporating beads to remove primer-dimers, enhance fluorescent signal and stop the reaction after amplification.

A SPICE-compatible simulation methodology for analyzing open– and closed-loop high-frequency electronic ballasts for fluorescent lamp was developed. The proposed procedure applies envelope simulation and makes use of the SPICE-compatible model of a fluorescent lamp. Experimental results validate the reliability of proposed simulation method.
