Abstract

This paper reports a multichannel high-power light-emitting diode (LED) driver employing a single-stage dc-dc power conversion and control technique with dimming capability. A half-bridge nonresonant converter with symmetrical quadrupler rectifier output is implemented to convert available dc power to multiple current regulated dc outputs for driving LED loads. The dc-dc power conversion efficiency of about 98% is obtained from advantageous operation of the converter with complete soft switching of all semiconductor devices and reduction in power conversion stages. The driver possesses inherent protection against LED failures due to its topology for both electrically open and short-circuit conditions of the LEDs. This patented converter is applicable for high-power LED lighting.
