LED Driver Based on Boost Circuit and LLC Converter

LED Driver Based on Boost Circuit and LLC Converter

In order to reduce the size and cost of a medium-power light-emitting diode (LED) driver, a novel single-stage LED driver integrating a boost converter with a half-bridge LLC resonant converter has been proposed. This topology is composed of a boost power factor correction circuit operating in a dis...
