Performance Evaluation of a Direct AC-DC Boost Converter for Piezo-Electric Energy Harvesting System

Abstract

Now a days, many of the researchers generate electricity from renewable energy resources in a natural way at the same time free of cost is expected and then current trends in renewable source power generation are more famous. If any changes in atmosphere or the unpleasant ecological (green) impact. The piezoelectric generator is one of the renewable energy sources. The mechanical stress is applied that can pull out the energy from piezoelectric material. The piezoelectric material can generate the milliwatt. Such that the output energy conversion level is very minimum. Here DC output voltage is needed. So the AC-DC boost converter and the DC-DC buck-boost converter can be used to get a perfect DC output. In that paper, bridge rectification is avoided and straightly converts the minimum ac input voltage into needed maximum dc output voltage level. This simulation is done by using a MATLAB.
