Design on 2kW Photovoltaic Power Used in Communication Base-Station Based on DSP28035

光伏电源为通信基站的直流负载提供电能,同时对蓄电池进行充电,因此,光伏电源的性能直接影响着通信基站的长期运行。在Buck电路的基础上,基于DSP28035和单片机STC12C5A56S2设计了通信基站2kW光伏电源。分别从硬件电路、软件程序以及最大功率跟踪对2kW光伏电源进行介绍,通过实验证明:光伏电源提高了太阳能的转换效率和蓄电池充放电的稳定性,对于太阳能发电在通信基站的推广和应用具有一定的推动作用。

The photovohaic power supplies power for DC load of the communication base-station, and charges the storage battery. So, it is important for the communication base-statiofi to run for long time. In this article, a 2kW photovoltaic power is designed based on Buck Circuit, DSP28035 and STC12C5A56S2. The hardware circuit, software program and maximum power point tracking （MPPT） of 2kW photovoltaic power are introduced and experiment is done. Experimental results proves that it increases the solar energy conversion efficiency and stability of the storage battery charging and discharging, plays certain promoting role in the promotion and practicability of photovohaic power generation.
