Power Converter Design for Maximum Power Transfer and Battery Management for Vibration-Based Energy Harvesting on Commercial Railcars
(Virginia Tech, 2015-06-24)
Although the locomotive of a train is energized, in general, other railcars are not. This prevents commercial rail companies from installing sensor equipment on the railcars. Thus, several different solutions have been ...
Energy Harvesting Circuit with Input Matching in Boundary Conduction Mode for Electromagnetic Generators
(Virginia Tech, 2018-09-24)
The proposed circuit intends to harvest kinetic energy from ElectroMagnetic Generators (EMGs). In order to extract maximum power from an EMG, an AC-DC boost rectifier is designed to match the impedance of the EMG. Rather ...
A Study on Energy Harvesters for Physical Unclonable Functions and Random Number Generation
(Virginia Tech, 2017-08-04)
As the broad implementation and use of wireless sensor nodes in Internet of Things (IOT) devices increase over the years, securing personal data becomes a growing issue. Physical unclonable functions (PUFs) and random ...
A New Approach to Wide Bandwidth Energy Harvesting for Piezoelectric Cantilever Based Harvesters
(Virginia Tech, 2013-03-27)
This thesis proposes a control system to widen the bandwidth of piezoelectric transducers (PZTs) for vibration energy harvesting while extracting maximum power. A straightforward complex conjugate match achieves maximum ...
