A Parameter Optimization Design Method Based on LCC Resonant Converter

摘要

For a fixed frequency LCC resonant converter have some problems of the full switching state of the lag arm is easily lost and the resonant current is large at heavy loads, resulting in only a narrow ZVS range and large conduction losses. Firstly, perform time domain analysis on the converter. Secondly, parameter design of LCC resonant converter based on fundamental analysis method using power analysis and time domain analysis. The parameter design method broadens the ZVS conduction range of the converter, and effectively reduces the resonant current and reduces the circulating current loss. Finally, a simulation platform is built in the Matlab/Simulink simulation environment. The simulation results verify the correctness of the theory.
