PRIMARY DRIVE SYNCHRONOUS HIGH-SPEED SWITCHING RECTIFYING CIRCUIT FOR LLC HALF-BRIDGE POWER CONVERTER FOR DRIVING LED

摘要

Disclosed herein is a secondary rectifier for an LLC half-bridge power converter for driving an LED, which provides a power converter with efficiency and stability higher than a conventional power converter using a rectifying diode. The LLC half-bridge power converter does not employ a fast recovery diode or a Schottky diode for secondary rectification and uses FETs as rectifying elements to achieve high efficiency, high stability and low cost and small volume.
