The brightness of discharge lamps is controlled by varying the frequency of the resonant converter for high efficiency operation. In this paper we introduce a resonant converter with a magnetic energy recovery switch along with power factor correction. The PFC converter generates DC voltage controlled by fuzzy controller as a feedback system connected to discharge lamp through high frequency resonant converter. The complete analysis with different frequencies and graphical representations of output voltage and current of the lamp are presented using MATLAB software with dynamic operating states.
