Abstract
Modern day electrification of the transport sector gives new challengens to the electric infrastructure. At the same time, electric energy storage on board vehicles and ships allow for new convenient and efficient solutions for charging and interaction with grids. Inductive power transfer (IPT) is a concept that is increasingly being developed and used in the transport sector. Systems for static and dynamic wireless charging of road and rail vehicles have been demonstrated with power levels ranging from a few kWs towards the MW-range [1]–[6]. IPT allows for contactless charging of the onboard battery by using automatic systems. Such systems have the prerequisites to be highly reliable and easy to use given the lack of moving parts and control systems for automatic start and stop of charging. Thus it is believed that IPT systems will play a bigger part in the infrastructure in the future.
