A dynamic conductance model of fluorescent lamp for electronic ballast design simulation

Summary form only given, as follows. In recent years, fluorescent lamps operating at high frequencies have emerged as an energy-efficient alternative to directly replace the incandescent lamps. Fluorescent lamps are operated at high frequencies for the advantages of higher lamp efficiency and longer life, and the electronic ballast that operates such lamps is essentially a power converter that transforms the mains power into highfrequency power. A dynamic conductance model of fluorescent lamp is presented. The model is based on an expression for the lamp conductance derived from the time-dependent ionization balance equation.
