Design on LED Driver Based on LLC Resonant Topology

Abstract:

As for the DC/DC part in high-effiency LED driver with constant current output, this paper presents the circuit based on LLC resonant topology. The principle of the LLC resonant converter, design process, and the influence of different key parameters to its performance are also prensented. Design considerations and experimental results are presented for a 200W LED driver prototype which demonstrating good performance and the efficiency of the LLC resont converter can be reached above 95%.
