Embodiment 1
[0032] The magnetic resonance wireless energy transmission system for active electromagnetic interference suppression and compensation in this embodiment has a structure as attached figure 1 As shown, the composition mainly includes the wireless energy transmission subsystem and the active electromagnetic interference suppression and compensation subsystem. side) and between the wireless energy transmission area. The composition of the wireless energy transmission subsystem includes a transmitting end module 5, a transmitting antenna 3 connected to the transmitting end module, a receiving end module 4 and a receiving antenna 2 connected to the receiving end module; both the receiving antenna and the transmitting antenna are coils The structural antenna is composed of N Litz wires of 0.1mm×200, and the coil planes of the receiving antenna and the transmitting antenna are arranged parallel and opposite to each other. The composition of the active electromagnetic interference su...
Embodiment 2
[0035] The magnetic resonance wireless energy transmission system for active electromagnetic interference suppression and compensation in this embodiment has a structure as attached image 3 As shown, the structure is basically the same as that of Embodiment 1, the difference is that the outer side of the transmitting antenna 3 and the receiving antenna 2 in the wireless energy transmission subsystem are provided with a ferrite 1 of the overall structure to reduce the wireless energy consumption. Electromagnetic leakage of energy transmission subsystems.
Embodiment 3
[0037] The magnetic resonance wireless energy transmission system for active electromagnetic interference suppression and compensation in this embodiment has a structure as attached Figure 4 As shown, the structure is basically the same as that of Embodiment 2, except that the outer side of the transmitting antenna 3 and the structure of the ferrite 1 provided on the receiving antenna 2 in the wireless energy transmission subsystem. The ferrite structure in this embodiment is a bulk structure ferrite dispersedly arranged to improve the heat dissipation performance of the ferrite, and is suitable for a high-power transmission system.
