A Dynamic Model for Contactless Energy Transfer Systems
2019 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW), 2019Inductive contactless energy transfer (CET) systems show a certain oscillating transient behavior of inrush currents on both system sides. This causes current overshoots in the electrical components and has to be considered for the system dimensioning.

Efficiency Factor Calculation for Contactless Energy Transfer Systems
2019 IEEE Wireless Power Transfer Conference (WPTC), 2019This paper proposes a simplified efficiency calculation method for contactless energy transmission systems, CET for short. The focus lies on the extension of the efficiency calculation for different reactive power compensated coil arrangements and the consideration of load dependencies. The proposed approach leads to simplified descriptions of the load-
