Research and implementation of LLC resonant soft switching high-frequency converter
In this paper,the topology of LLC resonant high frequency converter is analyzed,the tra-ditional DC voltage gain model is derived,and an improved method considering parasitic parameters of high frequency transformer and resonant inductor is proposed,a more accurate DC voltage gain model is obtained.Based on the proposed optimal gain model,the parameters of the resonant slot are calculated in detail.The simulation model is built by simulation software,and the theory is verified by simulation.Fi-nally,the hardware test platform is built.The results show that the LLC resonant soft-switching high-frequency converter can realize soft-switching,and has the characteristics of high precision voltage-stabilized output and high efficiency.
