Due to a lack of financial resources, we unfortunately have to suspend the import of
any new radio frequency and mobile phone-related articles as of now (November 27,
2017). We apologize for this inconvenience and will keep you informed.
Because we received a large number of inquiries, we set up a bank account to accept
donations. With their aid, we hope to resume, at least partly, the import of newly
published articles to the RF archive of the EMF-Portal. Any contribution is greatly
appreciated. Thank you for your kind support!
For the InductivePower Transfer (IPT) one primary and one secondary coil as well as a rectifier are required. The primary coil is thereby located on the ground beneath the vehicle and fed by alternating current. Due to the generated alternating magnetic field an alternating voltage is induced in the secondary coil which is positioned underneath the vehicle. The rectifier then converts the ACpower into DCpower before storage. Sometimes the vehicle has to be lowered for the sake of a more efficient energy transmission.
