摘要
介绍了研制的一种电动汽车用车载充电机的功率因素校正装置，主回路采用Boost型变换器，以L4981A作为功率因素校正的控制核心，对系统的主回路的参数进行了计算，设计了硬件的控制电路。样机实验结果表明，该系统获得了较高的功率因素和较好的动态性能，可靠性高。
The Power factor correction device on-borad chargerfor electric vehicles was developed. The main circuit using the Boost type use the L4981A as power factor correction control core. The main circuit of the system parameters were calculated and hardware control circuit is designed. Prototype experimental results show that the system have a high power factor and better dynamic performance.
