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

摘要

A Spice-compatible dynamic conductance model ofuda fluorescent lamp for use in electronic ballast simulation is presented.udThe time-dependent conductance of the fluorescent lamp isudderived 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.udSimulation results are compared to experimental measurements and satisfactory agreement is achieved.
