Study Experiment of Energy Harvesting System Based on Solar and Vibration
Abstract:
According to the theory of solar energy and vibration energy harvesting, an energy harvesting system based on energy conversion scavenging technology has been designed to convert the solar energy and vibration energy into the electric power. Piezoelectric materials and the solar cells are used as core power conversion section, and the system also consists of the lithium battery charge chip, the rectifier, comparators and switch chips as the control segments, combined with the super capacitor, etc. The energy harvesting experiment shows that the lithium battery can be charged through solar and vibration by the solar and vibration energy harvesting system, and the charging chip adopted in this work has input voltage limited current mode which can fulfill intermittent charge smoothly.
