Embodiment 1
[0033] Such as figure 1 with 2 As shown, a system that utilizes ferromagnetic resonance to realize wireless power transmission includes a power frequency AC power supply at the transmitting end, a primary coil of the ferromagnetic resonator at the transmitting end, a resonant capacitor at the transmitting end, a secondary coil of the ferromagnetic resonator at the receiving end, and a receiving end ferromagnetic resonator secondary coil. The resonant capacitor at the receiving end and the load at the receiving end, the primary coil of the ferromagnetic resonator at the transmitting end and the secondary coil of the ferromagnetic resonator at the receiving end are coupled and connected. The power-frequency AC power supply at the transmitting end is a 220V, 50Hz power-frequency single-phase AC power supply. Both the transmitting end of the ferromagnetic winding and the receiving end of the ferromagnetic winding are composed of copper wire wound ferromagnetically, and the induct...
