Abstract (en)

A system and method are provided for induction mediated energy transfer through a metal wall. A first metal plate shape (22) is arranged in a manner that a secondary coil (12) is located between the first metal plate shape (22) and the metal wall (13), wherein the first metal plate shape (22) follows the coil windings in tangential direction and comprises an isolation barrier (50) arranged between lateral sides of the first metal shape thereby preventing electric conduction across the barrier in a tangential direction. In an embodiment, a secondary magnetic field generator (23, 24) is positioned on the metal wall and adjacent opposite lateral sides of the first metal plate shape (22) thereby generating a secondary magnetic field (B2) extending into the wall along a contour between opposite lateral sides and directed between said lateral sides of the first metal plate shape so as to displace at least part of the primary magnetic field (B1) from the wall (13) and through the secondary coil (12).
