This paper presents a review of high-power-density non-resonant and resonant switched-capacitor (SC) converters topologies for driving organic-lighting-emitting-diode (OLEDs) lamps. These converters are light, small and cheaper in comparison with the linear power supplies and conventional DC-DC converters owing to the avoidance of large magnetic components. Resonant SC (RSC) converters show high efficiency and low EMI noise because they employ a small resonant inductor, which is connected in series with a switched capacitor in order to resonate at a frequency higher than switching frequency, thus allowing them to attain zero-current-switching (ZCS). The bidirectional step-up RSC converter has been identified as one of the best candidates to be used as an OLED driver. Simulation and experimental results from a laboratory prototype designed to supply a 60V 25W OLED lamp from a dc 30 V voltage source are presented.
