Summary
Under the generic term 'Next Generation Train - NGT' the German Aerospace Center (DLR) has introduced vehicle concepts for various railway applications. All train concepts have in common that the required energy is supposed to be supplied through a catenary-free energy transfer system that uses inductive power transmission. The transition from a sliding electrical contact to catenary-free current transmission requires fundamental changes to the overall design of the power supply system primarily due to the different energetic conversion processes needed for an inductive power transmission. However, existing technological limitations, especially power electronics, have a serious impact on the system design. The challenges related to the dimensioning of the track-side power supply system, considering technological limitations of today's equipment are discussed in this paper.
