Switched Capacitor Converter

This article discusses a switched capacitor-based converter to drive high power light emitting diodes (LEDs). The current pulse is provided by a switched capacitor, which is differing from that of conventional constant current dc drivers. The proposed approach differs from the traditional switched-capacitor-based one, because it uses a small inductor to improve the switching behaviour of the converter. The effects of switching devices on the proposed converter are evidenced and evaluated, based on the charge control analysis.Experimental results are presented and discussed to demonstrate the technical feasibility of the proposed MSC converter applied as LED driver through Matlab simulation and hardware result.
