摘要
太阳能光伏发电作为一种具有广阔前景的绿色能源已成为工业界和国内外学术界研究的热点,针对离网型光伏发电系统,分析了BOOST电路和BUCK电路在最大功率点跟踪(MPPT)电路中的缺点,提出了一种基于BOOS T-BUCK电路的蓄电池脉冲充电电路,采用P IC16F877单片机进行智能控制,并绘制了单片机控制的A/D采样电路及外围电路。实验结果表明:一是实现了对蓄电池的脉冲充电;二是与BOOST、BUCK电路相比,大大提高了系统的工作效率。
As a green energy, solar photovoltaic technology has a wide prospect and it has been the research hotspot in industrial circles and the academic circles. In this paper, a battery charging circuit controlled by PIC microcontroller for stand-alone photo -voltaic power generation was presented. The shortcomings of the BUCK and BOOST circuits applied in the MPPT circuit were analyzed. The experimental result shows that the pulse charging method is used to charge the battery, which can extend the life of battery and improve system efficiency.
