Abstract
LCD displays for notebook computers are backlit using cold cathode fluorescent lamps (CCFLs). An investigation of the LCC (series/parallel) resonant inverter as a potential power supply for these lamps is discussed. The attractiveness of this topology is primarily its simplicity compared to the widely used current-fed Royer oscillator based topologies. Experimental comparisons of LCC resonant inverter and Royer inverter performance are presented
