Optimization Research on Hybrid Control of Composite Three-level LLC Based on PLECS
In fuel cell and photovoltaic power generation, the input voltage of LLC converter varies widely. This paper proposes to change the voltage gain according to different input voltage ranges. By changing the LLC driving mode, the LLC converter switches among three sub modes: composite three-level mode, two-level full bridge mode and two-level half bridge mode. The voltage gain under different sub modes is derived, and the gain characteristics in a wide input voltage range are analyzed. At the same time, the PLECS simulation model is established to obtain the LLC working waveform, switch loss and voltage stress borne by the switch under three working modes. The simulation results verify that the variable topology LLC control scheme can maintain 48V constant voltage output under each working mode.
