Design of a radio energy transmission device

In order to solve the cost of wired transmission construction, low flexibility, weak convenience and other problems. We designed a kind of radio energy transmission device for strong coupling magnetic resonance mode based on the resonance principle. When the natural resonance frequency of two coils is equal to the system frequency, the strong magnetic coupling resonance is generated between the two coils in a certain distance to realize the wireless energy transmission. Finally, the transmission characteristics of the system are studied by simulation and experiment. The results show that under a certain distance, the wireless power transmission device has a larger output power and higher transmission efficiency, which can be used in a variety of work occasions.
