Three bipolar aerosol chargers, an AC-corona (Electrical Ionizer 1090, MSP Corp.), a soft X-ray (Advanced Aerosol Neutralizer 3087, TSI Inc.), and an α-radiation-based 241Am charger (tapcon & analysesysteme), were investigated on their charging performance of airborne nanoparticles. The charging probabilities for negatively and positively charged particles and the particle size conservation wer...

Wireless chargers are used to refill sensors’ power supply in a wireless rechargeable sensor network (WRSN) so that the WRSN can operate sustainably. Since wireless chargers are costly, the problem about how to deploy as few as possible chargers to make a WRSN sustainable is important. This paper proposes a greedy algorithm, named adaptive pair based greedy cone selection (APB-GCS), to consider...

Besides the integration of renewable energies, electric vehicles pose an additional challenge to modern power grids. However, can also be a flexibility source and contribute system stability. Today, still heavily relies on conventional technologies stay stable. In order operate future based energies only, we need understand potential assets such as become able use their flexibility. this paper,...

A high-performance contactless electrical energy transmission (CEET) technique which employs the inductive energy transmission principle is described. The proposed technique enables the implementation of high-efficiency high-power-density fully regulated CEET systems suitable for applications with a wide input and load range. A high efficiency of the system is achieved by recovering the energy ...

Recently, Plug-in Hybrid Electric Vehicles (PHEVs) have gathered a lot of attention by integrating an electric motor with Internal Combustion Engine (ICE) to minimize fuel consumption and greenhouse gas emissions. The On-Board Chargers (OBCs) are selected in this research because they limited dimensions mass, also consume low amounts power. Equivalent Series Resistance (ESR) filter capacitor is...

Rapid technological advances in the domain of Wireless Power Transfer pave the way for novel methods for power management in systems of wireless devices, and recent research works have already started considering algorithmic solutions for tackling emerging problems. In this paper, we investigate the problem of efficient and balanced Wireless Power Transfer in Wireless Sensor Networks. We employ...

A wireless rechargeable sensor network (WRSN) consists of sensor nodes that can harvest energy emitted from wireless chargers for refilling their batteries so that the WRSN can operate sustainably. This paper assumes wireless chargers are equipped with directional antennas, and are deployed on grid points of a fixed height to propose two heuristic algorithms solving the following wireless charg...
