Title Design of a energy harvesting and conversion device
Abstract In recent years, collection and use of different kinds of green energy becomes a hot topic.
After study in structure and interface circuit of energy harvesting, a high efficient hybrid energy harvesting device, including a piezoelectric, electromagnetic, and solar energy harvesting structure, and an improved energy harvesting circuit, has been designed in the dissertation to harvest and use vibration and solar energy. The output of the self-powered device is stable by adding feedback control. Experiments show that this device can harvest, convert and manage vibration and solar energy with high-efficiency of energy harvesting and output, and the efficiency of the improved circuit is much higher than the standard one.
Such a device with a wide range of purposes can be used in vehicular electronic devices, parking guidance systems, wireless sensor nodes, field operations, as well as other environment with green energy.
Keywords green energy, hybrid energy harvesting, vibration energy, solar energy, feedback control
