Current Technology of Electronic Ballasts for Fluorescent Lamps

Dynamic Interaction of High Frequency Electronic Ballasts and Fluorescent Lamps

Fluorescent lamps are non-linear devices that exhibit negative resistance over the useful range of operation. At low frequency, this negative resistance peculiarity is passed through during each period of the AC driving current [1]. When the fluorescent lamp operates at high frequency, the negative resistance is associated with the average power rather than with the instantaneous, cycle by cycl...

Some basic facts and some advanced information on ballasts for fluorescent lamps

Gas discharge lamps, this meaning lamps using the principle to make a gas electrically conductive and thereby light emitting, are a relatively old technique. Especially fluorescent lamps represent a very widespread lighting system. It is not possible to apply the line voltage directly to such lamp, be it AC or DC, a higher or a lower magnitude. Traditionally these lamps have always been operate...

Dynamic Interaction Analysis of HF Ballasts and Fluorescent Lamps Based on Envelope Simulation

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.
