摘要
介绍了应用于电动观光车充电器前级的一种APFC(Active Power Factor Correction)方案。基于UCC3818A控制电路,选用Boost拓扑,采用平均电流控制方式实现了电路设计。对电路工作原理和各部分功能设计做了简要的分析。实验表明,在600 W时PF(Power Factor)值能够达到0.984以上,该方案具有一定的应用参考价值。
An APFC scheme applied in the electric sightseeing car charger＇s front stage was described in this article. Based on the UCC3818A control circuit, it uses average current control mode to achieve the circuit design. The working principle and the function of each part of the circuit design was briefly analyzed. PF can reach more than 0.984 in 600 W, that was showed in the experiments. And this article hade certain application reference.
