摘要
光伏阵列的输出特性受太阳光强影响很大,弱光下,其电流输出很小,不能直接对蓄电池充电.为了使光伏组件能在弱光下工作,本文提出了一种基于组态优化的间歇脉冲充电法.作者采用了AVR单片机来实现该充电方法,并通过对硬件实验所获取的图像和数据的分析,证明该方法在弱光下能使光伏阵列有效地对蓄电池充电.
The output of the photovoltaic array is affected by the incident radiant intensity. Under weak sunlight conditions, the current is very small being unable to charge the storage battery directly. Considering that the solar module can work under the weak sunlight, a method of intermittent impulse-charging is presented based on the configuration optimization. A SCM（single chip micyoco） of AVR is employed to design the intermittent impulse-charger. Experiment images and data demonstrate the effective charge of the storage battery.
