Custom Maximum Power Point Tracker

The purpose of this project was to design a custom Maximum Power Point Tracker (MPPT) for an off-grid charging application. The custom MPPT used a DC/DC buck conversion topology controlled by a Pulse-Width-Modulated (PWM) signal. The duty cycle of this PWM signal was determined according to a Maximum Power Point Tracking algorithm set by a microcontroller. The implemented algorithm performed power calculations and allowed the solar panel to operate at its maximum efficiency. The design was mounted on a Printed Circuit Board and further testing showed that the algorithm was successful in determining the Maximum Power Point of the solar panel with an efficiency greater than 90 percent

Advanced Energy Harvesting Technologies

Energy harvesting is the conversion of unused or wasted energy in the ambient environment into useful electrical energy. It can be used to power small electronic systems such as wireless sensors and is beginning to enable the widespread and maintenance-free deployment of Internet of Things (IoT) technology. This Special Issue is a collection of the latest developments in both fundamental research and system-level integration. This Special Issue features two review papers, covering two of the hottest research topics in the area of energy harvesting: 3D-printed energy harvesting and triboelectric nanogenerators (TENGs). These papers provide a comprehensive survey of their respective research area, highlight the advantages of the technologies and point out challenges in future development. They are must-read papers for those who are active in these areas. This Special Issue also includes ten research papers covering a wide range of energy-harvesting techniques, including electromagnetic and piezoelectric wideband vibration, wind, current-carrying conductors, thermoelectric and solar energy harvesting, etc. Not only are the foundations of these novel energy-harvesting techniques investigated, but the numerical models, power-conditioning circuitry and real-world applications of these novel energy harvesting techniques are also presented

Solar Charging Station

The purpose of this project was to design and develop a proof of concept Solar Charging Station capable of delivering power to up to four cell phones and two laptop computers simultaneously. A custom maximum power point tracker (MPPT) was designed to extract the maximum amount of power available from the solar panels. This MPPT sampled the voltage and current output of the solar panels and executed the “perturb and observe” algorithm to determine the maximum power point

Grid-Connected Renewable Energy Sources

The use of renewable energy sources (RESs) is a need of global society. This editorial, and its associated Special Issue “Grid-Connected Renewable Energy Sources”, offers a compilation of some of the recent advances in the analysis of current power systems that are composed after the high penetration of distributed generation (DG) with different RESs. The focus is on both new control configurations and on novel methodologies for the optimal placement and sizing of DG. The eleven accepted papers certainly provide a good contribution to control deployments and methodologies for the allocation and sizing of DG
