The invention discloses a full-bridge LLC circuit. The full-bridge LLC circuit comprises a first module and a second module, wherein each of the first module and the second module comprises a switch bridge arm, a resonant bridge arm, a resonant inductor, a resonant capacitor, a transformer and a rectifier unit. The resonant capacitor in the first module and the resonant capacitor in the second module are connected, so that currents flowing through the resonant inductor of the first module and the resonant inductor of the second module are balanced, current peaks of secondary side output ends of the transformer are consistent, so that currents flowing through the resonant inductors in the full-bridge LLC circuit are balanced and the current peaks of the secondary side output ends of the transformer are consistent, and the MOS in the resonant groove is not burned. 本发明公开了种全桥LLC电路，包括：第模组和第二模组，第模组和第二模组均包括开关桥臂、谐振桥臂、谐振电感、谐振电容、变压器以及整流单元；采用本发明提供的全桥LLC电路，将第模组中的谐振电容与第二模组中的谐振电容连接，使得第模组中的谐振电感和第二模组中的谐振电感上流过的电流值相均衡，且变压器副边输出
