	Advanced Magnetic Energy Harvester for Charging Drones from Overhead Powerlines   By Viet DUONG HOANG, Emad EBEID	[View]   [Download]
Abstract: Recently, due to the advantages of drones, many electrical companies have employed drones for inspecting overhead transmission lines instead of helicopters. However, the limited operating time is still the big issue preventing drones from being used for monitoring on a large scale. The magnetic field around cables is a potential power source enabling drones to recharge when inspecting high-voltage power lines, eliminating the need to return to the home base for charging. In this paper, the Transfer Window Alignment method was combined with Perturb and Observe algorithm and Silicon Steel core to enhance the harvested power. The experiment showed that extra 58.6\% power could be harvested compared to the traditional approach. Regardless of the current fluctuation on the power lines, the proposed method also allows the charging circuit to automatically locate the maximum power point without sensing the primary current.
	Enhanced Power Management System Powered by Piezo Electric Energy Harvesters for Data Transmission Systems   By Mahmoud SHOUSHA, Andreas SCHORER, Martin SITTNER, Martin HAUG	[View]   [Download]
Abstract: This paper presents an enhanced power management system (PMS) for data transmission applications. The presented EHS is based on a low power non-inverting buckboost converter and provides maximum power point tracking and protection features. Compared to previous implementations [1]-[4], the presented PMS improves efficiency by up to 50\%, reduces first transmission time by 35\% and periodic transmission time by 17\%.
	Improvement in output power and frequency band for magnetostrictive vibrational generator with resonance capacitor   By Masataka MINAMI, Yuki HANAI, Shinichi MOTEGI, Masakazu MICHIHIRA, Toshiyuki UENO	[View]   [Download]
Abstract: Vibration power generation is one of the energy harvesting technologies. Vibration power generation has the two problems of low output power and changing vibration frequency. Therefore, this study proposes a resonance system that utilizes both mechanical and electrical resonance to improve output power and widen the frequency band
	Investigation of Gravitational Energy Harvesters for IoT Power Supply in Freight Train Monitoring   By Mirco LO MONACO, Caterina RUSSO, Aurelio SOMÀ	[View]   [Download]
Abstract: Recent advances in technology make energy harvesting a promising power supply solution for IoT devices. An electromagnetic gravitational energy harvester prototype for railway monitoring applications is proposed. The main components of the autonomous IoT sensorized node are described. Laboratory dynamic tests and simulations show the harvester resonance frequency and maximum scavenged power for supplying the node. Experimental vertical vibration data collected onboard of a freight railcar are used for harvester frequency tuning and real performance evaluation. The node power management and rectification system is studied to choose the best smoothing capacitor. Experimental battery charge tests under the real onboard excitations are performed and the duty cycle of the autonomous IoT node is defined.
