基于超级电容器的新型低频能量收集系统
资料介绍
对于低频可再生能源的收集需要考虑其比较大的内部阻抗,不规则的断续输入,受环境干扰等问题。本研究采用多级反馈式稳压升压技术,嵌入低功耗控制芯片算法控制对低频输入能量的最大功率点进行跟踪（MPPT）,同时超级电容器代替锂电池作为储能系统,应用互感耦合,从而达到高效收集、整流和输出的效果。因此本研究设计出的收集系统可高效地收集低频可再生能量,最大收集率可达91.16%,加入输入/输出隔离系统以提高带负载能力后其总收集效率达到了53.18%。
Designing novel harvesting system is necessary for collecting low-frequency renewable energy due to their environment dependent and intermittent characteristics. A strategy is proposed of using the multilevel feedback rectifying and BOOST/BUCK cir-cuits, low power control chip and software control algorithm to tracking maximum power of input low-frequency energy（ MPPT）,meanwhile, supercapacitors are used as energy storage devices to replacing the batteries. Finally, use current transformer, conse-quently, high efficiency to reach the effect of energy harvest, rectify and output. The results show that the maximum collecting effi-ciency is 91. 16 %, and that is 53. 18 % after integrating the input/output circuits for enhan...
