Abstract
A resonant, contactless, RF power coupling suitable for high power-density applications and for use in an ocean environment is disclosed. In the illustrative embodiment, the power coupling includes a transmit coupling and a receive coupling, each of which include a resonant element. A high-powered RF generator is coupled to the transmit coupling and a rectifier circuit is coupled to the output coupling. Each of the resonant elements is disposed in its own electrically-conductive canister and advantageously potted in an appropriate insulating dielectric. Each canister has an open end to facilitate inductive coupling between the two resonant elements. In order to exclude seawater from the interface between the canisters, a seal of compliant material is disposed therebetween.
