Harmonic model for the fluorescent lamp

This paper describes a method for modelling harmonic currents injected by fluorescent lamps. A model was developed using experimental results from commercially available lamps and takes into account the tube and ballast nonlinearities and their dependence on source voltage variations. A simulation method with the ability to analyse nonlinear networks is needed for this model. We proposed an extension to the iterative harmonic analysis (IHA) to calculate the harmonic currents injected by fluorescent lamps. The IHA algorithm is currently used to analyse the interaction between nonlinear converters and linear networks
