Design Based On RCC Circuit Of Dimmable LED Driver

In recent years,Lighting industry developing rapidly,New lighting system began to rise,LED lighting in gradually replace traditional lighting and lighting energy-saving lamps.LED lighting has the advantages of more energy efficient,and the driver as an important part of LED lighting,it has research significance.And RCC circuit has sample structure,low cost,high reliability,and it is convenient to realize multiple output and constant current control,it is very suitable for use in LED lighting driver design.RCC is Ringing Choke Converter,it can get reliable work just need a few discrete components,so it has a big advantage on cost than IC design.And LED lighting need a constant current driver that has good performance and low cost,RCC circuit can meet the request.This thesis research one LED lighting driver,and choose RCC circuit as this constant current driver.This paper introduced the operation principle of three topology of switching power at first,then analyzed in detail the working process of RCC circuit that based on three kinds of topolopy,Finally focus on RCC circuit optimization design and practical design method.
