摘要

提出了一种新的电池充电系统拓扑结构。拓扑结构由三部分组成。第一部分采用单周期控制方式，它具有功率因数控制的功能，还可以提高系统的功率因数。第二部分采用LLC谐振技术，使开关ZVS和整流二极管ZCS在二次侧。降低了开关损耗，提高了系统效率。第三部分采用双向DC-DC拓扑结构，可以实现正/负脉冲快速充电。在MATLAB和PSIM中对该拓扑进行了仿真，提高了系统的功率因数和效率。

Positive/Negative Pulse Charging Technology of Battery Based on PFC-LLC Topology

A new topology is proposed as battery charging system. The topology has three parts. The first part uses the one-cycle control method, it has a function of power factor control, it also can improve the power factor of the system. The second part use the LLC resonance technology, it can make the switch ZVS and the rectifier diode ZCS in the secondary side. The switching loss is reduced and the efficiency of the system is improved. The third part use a bi-directional DC-DC topology, it can achieve the Positive/negative pulse fast charging. The topology has been simulated in the MATLAB and PSIM, the power factor and the system efficiency have been improved.
