【 摘 要 】

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 circuits, 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 ,consequently, high efficiency to reach the effect of energy harvest, rectify and output. The results show that the maximum collecting efficiency is 91.16%, and that is 53.18% after integrating the input/output circuits for enhancing capability of driving loads.
