电流型电场耦合无线电能传输技术
The Current-type Capacitively Coupled Wireless Power Transfer Technology
摘要
Abstract
ABSTRACT:In order to improve the output stability of the capacitively coupled wireless power transmission network, a current-type capacitively coupled wireless power transmission network was proposed. Through the design of the impedance matching network before the coupled capacitor, coupling current is almost approximately invariant with the change of the load impedance and the coupling capacitance under fixed operating frequency. Therefore, the relatively complex frequency tracking technologies is avoided. At the receiving terminal, both voltage-type and current-type output can be realized, through the property design of magnetic coupling impedance transformation circuit, so as to satisfy the demands of different type load. Under reasonable assumptions, the circuit models of the network were built, and the design methods of main parameter were obtained. The correctness of the working principle and the design method of the network were verified by means of both simulation and experiment.关键词
