Abstract:This paper proposes a high-efficiency LED driver consisting of interleaved buck-boost and buck converters. With no need to use any auxiliary reactive components, the active switches can operate at zero-voltage switching on (ZVS). The buck-boost converter is operated at discontinuous-conduction mode (DCM) to perform the function of power-factor correction (PFC). The buck converter regulates the output voltage to drive LEDs. A prototype 60-W LED driver is built and tested. Experimental results show that the swit… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
