Contactless power transfer (CPT) is an emerging topic which relies in high frequency resonant inverters to transfer power from a transmitter to a physically separated receiver inductively. Capacitive compensations on both the primary and secondary sides of a loosely coupled transformer are usually employed in recent researches in order to enhance the power transfer capability and the system efficiency...
This paper describes two methods intended to obtain the coupling factor k of an inductive coupling stage constructed to transfer power to a load in a 2-kW experimental prototype designed for wireless battery charging of electric vehicles. The air gap between the primary and the secondary windings of the inductive coupling is set to 125 mm. The first approach, purely analytical, relies on Neumann's...
The growing awareness that the use of fossil fuels is limited in time and that the growing awareness of the world population about environmental issues have been accelerating the search for environmentally friendly solutions that can contribute to decrease the oil dependency. Considering the world panorama of the transportation sector, mainly their pollutant emissions and oil consumption, different...
This research is developed the electric vehicle by the fuel cell. Between fuel cell source and motor controller, we add new power converter, offer steady output voltage to motor controller and drive the direct current hub motor. Converter not only offers steady output voltage but it also combines with coupling inductance technology to battery charger. Besides offers energy to drive motor, and fuel...
