一种无电解电容照明LED驱动电源设计
Design of LED driver power without electrolytic capacitor
摘要
Abstract
Though the high request of long life of LED for its corresponding driver's service life,the electrolytic capacitor restricted the service life of the LED driver,making the LED long life become meaningless.A LED drive power scheme without electrolytic capacitor was proposed.Compared with other electrolytic capacitor-less LED driver,the proposed topology removed electrolytic capacitor,the circuit structure was simple,and high input power factor and flicker-free could be achieved.The operation principle was introduced,and the experimental verification was carried on.关键词
