Design of Safe Wireless Power Transfer Systems for Electric Vehicles
Paper in proceedings, 2018

Wireless charging of electric vehicles is convenient but in order to makeit safe the exposure of humans to electro-magnetic fields mustbe below acceptable limits. We have designed a prototypesystem that transmits 3 kW with an efficiency of 85% where the magnetic fields around and inside the vehicle arebelow the EU councilrecommenda-tion of 6.25 μTat 85 kHz.
