摘要(Abstract)：
以太阳能发电为出发点,结合当前新的功率型LED节能照明技术,对基于太阳能发电的独立光伏LED照明系统的BUCK变换器中DC/DC变换电路进行了参数设计、仿真验证和具体实验分析。通过仿真,得出导纳增量控制法具有最大功率点运行平稳、波动小,当周围环境变化时可以迅速跟踪的优点。最后,通过实验对系统中设计的DC/DC变换电路进行了验证及分析,符合设计要求。该系统能应用在道路照明、庭院照明以及室内照明等,在电力输送困难的边远山区的道路照明和室内照明具有较强的实用性。
By combing the technology of solar electrical energy generation with the latest energy conserving lightning technology of power LEDs,parameter designs,emulation and experiment to the DC/DC converting circuits of the Buck convertor in the independent photovoltaic LED lighting system powered by the solar power generation are made in the paper. The simulation results show that the incremental conductance method has the advantages of stable operation and small fluctuation of at the maximum power point as well as prompt tracking to the variation of the circumstance. The experiment demonstrates that the DC/DC converting circuit design in the independent photovoltaic LED lighting system conforms to the specifications and design requirements. The system has very strong practicability and can be widely used in road,ourtyard and indoor lighting,especially in remote mountainous areas of transport difficulties in electric lighting and interior lighting.
