Function The lamp ignites when the voltage accros the lamp is larger than Vignition. The lamp burns with an arc voltage equal to Vburn and a negative voltage current slope defiend by NegativeResistance
Special Be carefull with specifying Negative Resistance. Start with 1, run a simulatio and check the current and voltage waveforms. The Negative Resitance is limited to -Vburn/Iburn After checking the waveforms you can me Negative resistance gradually negative, to meet the HCFL specifications.
