Capacitive Coupling Wireless Energy Transmission Constant Voltage System Based On Composite Network Resonance

Abstract

Electric field coupling wireless energy transmission is a way of transmitting electric energy wirelessly through a high-energy electric field as the energy medium. In actual application scenarios, the load situation is complex and changeable, and the static load has great limitations. In the case of load changes, the system can still provide a stable voltage power supply has become a top priority. Based on this idea, this article designed a capacitive coupling impedance matching structure that can keep the system stable under dynamic loads. Finally, the feasibility of capacitive coupling power supply was verified through simulink, and through the establishment of an experimental model, the energy transmission of 6W can be completed under a load of $10\Omega$, and the transmission efficiency can reach 80%.
