Abstract
A wireless power transfer apparatus for capacitive-inductive power transfer has a primary and a secondary device separated by the conductive member. The primary device has at least two transmitter plates configured to be capacitively coupled with the conductive member to induce a current flow and generate a magnetic field in the conductive member. The secondary device is connectable to a load and provided with a receiving coil configured to be inductively coupled with the conductive member.
