Abstract:A compact and high efficient LED driver compatible with various electronic ballasts commercially used in markets is newly proposed, which modulates the LED power by controlling a switching duty cycle of a main switch in synchronous voltage doubler rectifier. Thus, the fluorescent lamp can be replaced with the LED lamp without any change of fluorescent lamp fixture. The zero voltage switching (ZVS) is achieved for different switching frequency of electronic ballast, which leads to high efficiency. Furthermore, … Show more
