Control method of bifurcation based on three level LLC resonant charging circuit

With the rapid increase in the number of electric vehicles, V2G model has been widely concerned. In this paper, the three-level LLC resonant DC/DC converter applied to V2G is chosen as the research object. The charging process of the circuit is introduced from the basic principle of the circuit. Afterwards, MATLAB/Simulink is used to simulate and analyze the bifurcation phenomenon. Finally, it controls the bifurcation behavior and analyzes the waveform of the charged current after treatment. The results show that the new control method is effective.
