The main purpose of this paper is to develop a novel application of a resonant switch converter for battery chargers. A zero-current-switching ZCS converter with a quasiresonant converter QRC was used as the main structure. The proposed ZCS dc–dc battery charger has a straightforward structure, low cost, easy control, and high efficiency. The operating principles and design procedure of the pro...

Electric agglomeration is the process in which particles are charged in electric fields and coagulate, which is enhanced by electric force or turbulence. The collection efficiency of submicron particles is improved, which can be a solution to submicron particle abatement in traditional electrostatic precipitators (ESPs), by using a pre-charger to increase median particle diameter and realizing ...

Recently, adopting mobile energy chargers to replenish the energy supply of sensor nodes in wireless sensor networks has gained increasing attention from the research community. Different from energy harvesting systems, the utilization of mobile energy chargers is able to provide more reliable energy supply than the dynamic energy harvested from the surrounding environment. While pioneering wor...

Quantum battery works as a micro- or nanodevice to store and redistribute energy at the quantum level. Here we propose spin-charger protocol, in which cells are charged by finite number of spins through general Heisenberg $XY$ interaction. Under isotropic interaction, protocol is endowed with higher capacity terms maximum stored than conventional protocols, where continuous-variable system, e.g...

Introduction Rechargeable batteries are present in a variety of devices. The act of recharging them generally involves a charger wired to a wall outlet being plugged into the device. The charger can determine the type of charge the batteries receive and therefore determine the cycle life of the batteries. Wireless power transfer is on the cutting edge of the battery charging world. There are el...

This paper demonstrates a novel method which will automatically track the sun’s position and accordingly change the direction of the solar panel to get the maximum output from the solar cell. As solar energy becomes increasingly popular in all parts of the world, all kinds of solar powered products are flooding the renewable energy market. One of them is the solar panel battery charger, the env...

The battery charging system is a critical part of a plug-in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, c...

As the usage of cell phones is markedly increasing worldwide, accidental injuries and even lethal damages caused by cellular phone explosions have been reported lately. Although, cell phone charger explosion related scalding and tissue loss is extremely rare, they generally cause severe damage to tissues and cause severe complications, ending up in hospitalization. We are presenting a case of 9...
