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

By K.H. Loo, D.A. Stone, R.C. Tozer and R. Devonshire

Abstract

A Spice-compatible dynamic conductance model of\ud a fluorescent lamp for use in electronic ballast simulation is presented.\ud The time-dependent conductance of the fluorescent lamp is\ud derived from a plasma ionization balance equation that uses simplified descriptions of the physical processes within the lamp as its basis. The model has been designed to enable user-defined lamp radius, length, buffer gas pressure and cold-spot temperature as input parameters thus representing a valuable tool for ballast simulations.\ud Simulation results are compared to experimental measurements and satisfactory agreement is achieved
