WIRELESS ENERGY TRANSMISSION DEVICE WITH NOISE REDUCTION DESIGN

摘要

A wireless energy transmission device with a noise reduction design, relating to the technical field of wireless energy transmissions. The wireless energy transmission device comprises a stabilized potential eddy current damper (105). The stabilized potential eddy current damper (105) is close to a wireless energy transmission coil assembly, and is connected to an alternating-current low-resistance fixed electric plane (119) of a power conversion circuit board (101) by means of a conductor (103). By means of a high-frequency alternating-current cable (102) of a special structure, the transmission impedance of switch edge frequency and frequency multiplication of the power conversion circuit is improved, and an interference signal of the switch edge frequency and the frequency multiplication of the power conversion circuit is suppressed. By providing the stabilized potential eddy current damper, the potential of the wireless energy transmission coil assembly is stabilized, the alternating current of the operating frequency multiplication of the power transmission circuit is suppressed, and the related electromagnetic interference is greatly reduced. The high-frequency alternating-current impedance is improved in a wide range, an electromagnetic interference signal is reduced, and therefore, an electromagnetic interference problem is solved.
