摘要
介绍了一种小功率风光互补充电控制器。该控制器能有效降低损耗,充分利用风能和太阳能,效率更高。对风力充电而言,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至后级给蓄电池充电。对光伏充电而言,直接利用光伏充电器的后级进行充电。最后通过300 W风光互补充电系统的实验结果验证了设计的正确性。
A low-power wind and solar charge controllers is introduced.The controller reduces loss,and the wind power and solar energy is efficiently used.For the wind charging,when wind speed is low,rectifier output voltage will rise to a constant value and then sent to circuit by Boost chopper.When the wind speed is high,the Boost circuit is cut off,the rectifier output voltage is sent directly to the battery after the class charge.For the photovoltaic charging,solar charger is directly used to charge after the class.Finally,300 W wind and solar charging system experimental results verify the correctness of the design.
