title = "Magnetic Design of a Q-Coil for a 10 kW DDQ System for Inductive Power Transfer",
abstract = "To establish inductive charging for electric vehicles in public spaces, interoperable charging for a specified power class regardless of the coil topologies has to be guaranteed. The magnetic coupling of bipolar Double-D and circular coil combinations without an offset is very low. Hence, the power transfer capability is limited and performance as well as interoperability is poor. In this paper finite element analysis is used to enhance a Double-D coil system with a circular coil to get a so-called DDQ topology. It allows interoperable operation between the primary and both coil topologies on the secondary at high magnetic efficiency. First, the geometric dimensions are obtained with respect to coupling factor and maximum output power. Secondly, expected system behavior is analyzed to derive the winding turn number and the final O-coil shape.",
