Abstract：Half-bridge LLC resonant converter of high efficiency and high power density is widely used to drive the LED light source. Through the analysis of its principle, characterization and the resonant network transmission efficiency, we summed up a simple parameter design method. This method designs the LLC half-bridge resonant circuit of 100kHz and 120W with 90% conversion efficiency. The results of experiment confirm the feasibility of the design method.
