摘要

针对72V, 60Ah的锂离子电池，提出了一种新型拓扑“双输入通用llc谐振槽式充电器”。采用四个有源开关，拓扑结构为双半桥LLC电路。这种设计通过允许两个源共享相同的谐振槽来将能量传递给负载，从而消除了对额外电路组件的需要。转换器在差动模式下工作。采用简单的PI控制器进行电流控制变频控制，以调节电池在不同线路和负载扰动下的充电。利用MATLAB/SIMULINK对所提出的3.3kW充电器进行了仿真研究。

Dual Input Common LLC-Resonant Tank based off-Grid Charger

The paper proposes novel topology “dual input common LLC-resonant tank-based charger for charging the 72V, 60Ah Lithium-ion battery. With four active switches, the topology is a twin half-bridge LLC circuit. This design eliminates the need for additional circuit components by allowing the two sources to share the same resonant tank for transferring energy to the load. The converter is operating in differential mode. Current controlled Variable frequency control using simple PI controller is employed to regulate battery charging at different line and load perturbations. A simulation study is done on 3.3kW proposed charger using MATLAB/SIMULINK to support the theoretical concept.
