TRAILING EDGE DIMMER COMPATIBILITY WITH DIMMER HIGH RESISTANCE PREDICTION

摘要

Electronic system (100) including a controller (402), which provides compatibility between an electronic light source (410) and a trailing edge dimmer (404). The controller is capable of predicting an estimated occurrence < a trailing edge of a phase cut AC voltage and accelerating a transition of the phase cut voltage from the trailing edge to a predetermined voltage treshold. The controller predicts an estimated occurrence of the trailing edge of the phase cut AC voltage on the basis of actual observations from one or more previous cycles of the phase cut AC voltage.
