Development and simulation of dynamic conductance based wattage-independent Compact Fluorescent Lamp model in high frequency environment

This paper presents Simulink simulation of a dynamic conductance based wattage independent Compact Fluorescent Lamp (CFL) model in high frequency environment. In this context, the wattage independent model is developed by modifying the existing dynamic conductance model: the model coefficients are replaced by four polynomial equations derived from experimental data. After validating the developed wattage independent lamp model at low frequency (50 Hz), the electrical characteristics of the same model is simulated at high frequency (30 kHz) environment. Here the lamp is driven by electronic ballast consisting of half bridge inverter. Simulation results explore the applicability of the same wattage independent lamp model in both low (50Hz) and high (30 kHz) frequency operation and may be used for ballast design.
