基于串联谐振变换器的多通道LED驱动器，具有固有电流平衡和调光功能

This study proposes a high-efficiency light-emitting-diode (LED) driver based on the series resonant converter (SRC) topology. As the major requirement from LED driver circuits is the ability of providing constant current for maintaining a certain luminescence level, it is utilized that the SRC operates as a frequency-controlled constant current source when the switching frequency is lower than ha...
