摘要
通常情况下,新型微能源的功率有限且不稳定,其电压及电流都较小,这使能量的变换和收获存在一定困难.针对这个问题,介绍了一种利用直流升压芯片的充电电路,将这种低电压、弱电流的微能源高效储存起来再集中释放,从而实现微能源的收获及有效利用.
The power of new micro-energy is usually limited and unstable,and its voltage and current are relatively small,which can lead to the difficulty in energy conversion and harvesting.To solve the problem,the paper introduces a kind of charging circuit that make use of the direct-current voltage booster chip,which can effectively store up this kind of low voltage and weak current micro-energy,and then release it in a concentrative way,and thus the micro-energy is efficiently harvested and utilized.
