【 摘 要 】

Transmission distance is a key factor in designing a wireless energy transmission system. The change in coil spacing will have a huge impact on the output characteristics of the system.Therefore, this paper theoretically analyzes the mutual inductance model of two coils from the perspective of circuit theory.Studies have shown that coil spacing, impedance, self-inductance, operating frequency, load resistance and many other factors can affect the output characteristics of the system.So, this thesis uses the control variable method to study the relationship between transmission distance and output characteristics, and proposes the optimal output power point.Finally, an experimental prototype was made to verify the feasibility of the method.
