对超大容量蓄电池充电站的优化设计

针对目前众多超大容量蓄电池充电站采用相控整流技术存在网侧谐波污染严重,直流纹波大,充电终了深控运行功率因数低等缺陷,基于模块化设计思想,将自动有源功率因数校正（APFC）和高频整流技术结合,在控制网侧谐波和提高直流输出电能质量的基础上,设计了基于CAN总线的多开关电源均流超大容量充电系统,并进行了仿真和样机试验。仿真与试验结果表明,该优化设计可有效改善超大容量充电站的各项性能指标。

An optimized design for a storage battery charging station with super capacity

Aiming at a series of shortages such as the serious pollution of harmonic waves from grid side, high DC ripple and low power factor at charging end etc, which are caused by the phase control technology used in the charging station for batteries with super capacity, this paper brings out an optimized design for charging stations of a kind. Based on modularization idea and current sharing of CAN bus, the design improves the direct current quality and controls the harmonic wave pollution by utilizing active power factor correction（APFC） and high frequency rectifying technology. Meanwhile, some tests were done for simulation and sample machines, and the result obtained from the tests proved the design to be practical.
