Abstract
A system comprising a contactless power transfer system is presented. The system includes a primary element, a secondary element, and at least one field-focusing element interposed between the primary element and the secondary element and configured to focus a magnetic field. A partition is disposed between the primary element and the secondary element. The contactless power transfer system is disposed within pressure isolation cavities of a sub-sea assembly and configured to transfer power between a power source and a load.

11. A system comprising:
-
a contactless power transfer system comprising a primary element, a secondary element, a first field-focusing element disposed proximate the primary element, and a second field-focusing element disposed proximate the secondary element, the first and second field-focusing elements being configured for operating at two different resonant frequencies to focus a magnetic field and exchange power between the primary element and the secondary element. - View Dependent Claims (12, 13, 14, 15)

16. A contactless power transfer system comprising:
-
a primary element; a power source and a first filter coupled to the primary element and configured to transmit power at a first resonant frequency; a secondary element; a first converter and a rectifier coupled to the secondary element and configured to deliver power to a load; one or more sensors and second filters coupled to the secondary element and configured to sense at least one parameter and transmit data at a second resonant frequency; at least two field-focusing elements interposed between the primary element and the secondary element, a first field-focusing element configured for transmitting power at the first resonant frequency and a second field-focusing element configured for transmitting data at the second resonant frequency; and a second converter coupled to the primary element to receive data from the one or more sensors. - View Dependent Claims (17, 18, 19, 20, 21)
