Abstract
An inductive resonant wireless charging system includes a resonant wireless charging transmitting device, a wireless charging relay device and an inductive wireless charging receiving device. The resonant wireless charging transmitting device transmits a high-frequency radio frequency wave. The wireless charging relay device receives the high-frequency radio frequency wave using an electromagnetic resonance way, and converts the high-frequency radio frequency wave into a low-frequency radio frequency wave to transmit the low-frequency radio frequency wave. The inductive wireless charging receiving device receives the low-frequency radio frequency wave in a manner of electromagnetic induction.
