Abstract
An adaptive compensation circuit for controlling a universal lamp driver coupled to a lamp is disclosed. The adaptive compensation circuit utilizes an identification of a lamp type of the lamp to thereby generate a signal indicative of a time constant of the lamp. The adaptive compensation circuit subsequently determines a zero position and a pair of pole positions corresponding to the time constant, and generates a control voltage in response to a determination of the zero position and the pair of pole positions. The control voltage facilitates an operation of the universal lamp driver to stably provide a lamp current to the lamp.
