WIRELESS ENERGY TRANSMISSION DEVICE WITH NOISE REDUCTION DESIGN

摘要

A wireless power transfer device with EMI suppression includes a power conversion circuit board, a wireless power transfer coil group assembly and an eddy current damper (ECD) with a stable potential. The ECD is close to the wireless power transfer coil group assembly and is connected to a low-alternating current (AC) impedance direct current (DC) plane of the power conversion circuit board through a conductor.
