A dynamic model for the electrical characteristics of fluorescent lamps

A model for the electrical behavior of fluorescent lamps at standard line frequency (50 Hz or 60 Hz) and at high frequency (20 kHz-50 kHz). The model is based on the following three relationships: the lamp's V-I characteristic at high frequency; the lamp's DC V-I characteristic; and the dynamic relationship between these two modes of operation. The first two are readily measured using simple lab setups, and the third is assumed linear and first order. The model is empirical, and its parameters do not correlate with physical lamp characteristics such as lamp length, diameter, or gas pressure. Most aspects of lamp operation, including operation at high frequency, line frequency, and DC, have been successfully modeled. The model was used with a numerical circuit simulator to model fluorescent lamp operation in electrical circuits.<<ETX>>
