In this paper the possibility of achieving a coupling-independent operating regime for a Wireless Power Transfer Link based on resonant inductive coupling is theoretically and experimentally investigated. The two different cases of a link using either asynchronous or synchronous resonators are analyzed and discussed. It is shown that a coupling-independent regime can be realized by an appropriate selection of the operating frequency of a synchronous WPT link having a coupling coefficient above a critical value which depends on the resistive load of the link.

Abstract
In this paper the possibility of achieving a coupling-independent operating regime for a Wireless Power Transfer Link based on resonant inductive coupling is theoretically and experimentally investigated. The two different cases of a link using either asynchronous or synchronous resonators are analyzed and discussed. It is shown that a coupling-independent regime can be realized by an appropriate selection of the operating frequency of a synchronous WPT link having a coupling coefficient above a critical value which depends on the resistive load of the link.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
