Abstract
The aim of this paper is to analyze the sensitivity of various compact fluorescent lamps (CFLs) which are used in residential and commercial applications during voltage sags. Laboratory tests were performed on different CFLs commonly available in the market. The tests are based on recent testing standards and utilizing a modern industrial power corruptor. For predefined malfunction criterion of zero illuminance condition, sag depth and duration are varied to construct individual voltage immunity curves. Experimental results show that all CFLs are sensitive to voltage sags and vary in a wide range. It also proves that some brands of CFLs having similar power rating are sensitive to both sag magnitudes and its duration. Finally a method to improve the sensitivity of CFLs to voltage sags is implemented. This technique increases the holdup time of the dc bus voltage by connecting additional dc capacitance at the rectifier output of the CFL's ballast circuit.
