Design and Implementation of a Single Stage AC-DC Energy Harvesting Converter for Microgenerator
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
In this project, a direct ac-dc power electronic convertor topology is proposed for efficient and optimum energy harvesting from low – voltage micro generators. The convertor utilizes the bidirectional current - conduction capability of MOSFETs to avoid the use of a front – end bridge rectifier. It is operated in the discontinuous conduction mode and offers a resistive load to the micro generator. In this project, a chip has been designed and tested to demonstrate the feasibility of operating a digital system from power generated by vibrations in its environment. Then, two direct ac-dc power electronic convertor topologies are proposed for low voltage micro generators. These two are mainly used in designing the convertor for energy harvesting. The main application of this convertor is used in pacemaker. For this purpose currently we are using lithium battery to give pulse to heart muscles. But this battery is not chargeable. In this we are designing convertor for low voltage energy harvesting especially for pacemaker applications. The future work is that the closed loop of energy harvesting convertor for micro generator can be developed using artificial intelligent technique controllers like fuzzy logic controller, neural network, and genetic algorithms and can be compared with conventional controllers like PI, PID controllers.
