小功率风力充电控制器

Small wind charging controller

介绍了一种小功率风力充电控制器。相对于传统的基于Boost变换器的充电方式,该控制器有效地降低了损耗,能更加充分地利用风能;在风速较低时,通过Boost斩波器将整流输出电压升至一定值,再送至后级电路;当风速较高时,切断Boost电路,将整流输出电压直接送到后级给蓄电池充电。经过300 W风力充电系统的实验,验证了其设计的正确性。

A low-power wind charging controller is introduced, by comparison with traditional charging method based on Boost converter, the controller reduces wear and tear, could realize more fully using of wind energy. When the wind speed is low, by Boost chopper, the rectification output voltage will be raised to certain value and then will be sent to the later circuit; when the wind speed is high, it will cut the Boost circuit, and send the rectification output voltage directly to the battery for charging. Finally, the experimental results in a 300 W wind charging system verify the correctness of the design.
