Comparison between Different Discharge Lamp Models Based on Lamp Dynamic Conductance

Discharge lamp models based on dynamic lamp conductance are derived from physical equations that describe lamp behaviour. Lamp constructive data are not necessary to build the models, just lamp current and voltage data are necessary. In addition, these models have a relatively low complexity and not much calculation time is necessary to obtain them. They can be used to simulate low and high pressure lamps at low and high (20 kHz < f < 1 MHz) frequencies. Two of these models, derived from different physical equations, are tested and compared using fluorescent and HPS Na lamps.
