Designing of Simulink Model for Low Power Devices using Different Sources

Abstract

In the recent years, obtaining a sustainable form of energy to power various autonomous wireless & portable devices is increasingly becoming a matter of concern & various alternate sources of energy have been explored. The concept of power harvesting works towards developing self-powered devices that do not require replaceable power supplies. This paper represents energy harvesting using various energy renewable resources which include solar, wind, thermoelectric and piezoelectric. The system designed in Matlab Simulink environment and their energy combined and then transferred to small grid. In this system in near future RF module can also be integrated so that if out of these module none of them able to provide sufficient amount of energy then through RF link adequate amount of energy can be received so that low power devices can be driven.
