Title: VOLTAGE AND CURRENT COMPENSATION IN AN INDUCTIVE POWER TRANSFER UNIT
Abstract:
The invention relates to an inductive power transfer unit having a winding unit for inductive power transfer during a power transfer operation, flux guiding means, and an antenna element. It is an objective of the invention to provide for at least one additional antenna element at reduced costs and preferably with only little additional space required to install the additional antenna element and it is another objective of the invention to prevent damage to the antenna element during the power transfer operation. These problems are solved by providing an inductive power transfer unit (2, 3) wherein the antenna element (10) is arranged with the flux guiding means (6) for generating or receiving an antenna signal (50) during an auxiliary operation, wherein a compensation element (20) is arranged, such that the compensation element (20) compensates for an induced voltage and/or induced current in the antenna element (10) during the power transfer operation.
