Abstract
- A CLCL resonant dc/dc converter has been proposed and analyzed in this paper for two-stage light-emitting diode (LED) drivers. The circuit performs zero-voltage-switching (ZVS) turn-on and quasi-zero-current-switching (ZCS) turn-off. Then, a two-stage system has been designed using a power factor correction circuit before the proposed converter. Optimum input impedance angle, dead time, and components parameters have been achieved after thoughtful design, thus obtaining good soft-switching performance and reduced voltage stress. A 100-W prototype has been realized and tested demonstrating its high feasibility and efficiency at full load and during dimming operations. [ABSTRACT FROM PUBLISHER]
