Study of Full-bridge Resonant Converter Based on Dual Asymmetric Half-bridge LLC
The full-bridge resonant converter with dual asymmetric half-bridge LLC is an improved LLC resonant converter with fixed frequency control and a high-efficiency converter.This paper introduces the problems of asymmetric half-bridge LLC resonant converters and includes a detailed analysis of the operating principle,operating mode,and parameter selection of the dual asymmetric half-bridge LLC circuit.As well as the simulation tests of the converter model based on the selected device parameters.The results show that the converter can reduce the superimposed circulating losses of the excitation current,turn-off losses and zero-voltage conduction non-capacitance losses,greatly improving the conversion efficiency.
