Contactless energy transfer for main-line rail vehicles
2015In the context of an increasing importance of electric mobility with the aim to reduce greenhouse gas and noise emissions, railway operators intensify efforts to replace diesel vehicles with locally emission-free electric traction. Therefore more and more tracks need to be electrified. These electrified lines are the primary object of this paper.

Contactless energy transfer through air by means of ultrasound
IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011An alternative approach to the wireless transfer of energy is proposed, employing acoustic waves in air. Unlike conventional methods, acoustic energy transfer is able to achieve energy transfer at high efficiencies over distances that are large in comparison to the dimensions of the transmitter and the receiver.
