| Abstract: | As the technology of LED component develops,LED lighting is gradually becoming more popular in residential application. LED needs to be driven by constant current driver,so the design of LED driving circuit is one of the key technologies.This paper elaborates an optimized flyback circuit to improve the optical quality of LED luminaire,which can control the total harmonic in input current to 16. 1% and the luminance fluctuation to 3% by an integrated TOP structure of PFC Flyback combining DC /DC convertor design. |
