Original Abstract

This paper presents a modeling approach for FL ballasts and LED drivers with adjustable topology and feedback control of switching converter stages suitable for flicker sensitivity studies. The driver model is based on switch-averaging modeling principle. Together with a generalized lamp model it can be used to estimate flicker level of given driver and lamp combination. Out of eight driver classes identified in related literature, the model is fitted – and thus verified – on two classes, the first corresponding to a current-controlled DC-DC converter and consisting of one active, closed-loop controlled, converter stage, the latter corresponding to two stage closed-loop controlled driver.
