DETECTING AN OBJECT IN AN INDUCTIVE POWER TRANSFER AREA

摘要

The invention relates to a detector arrangement (3, 101) for detecting an object (203), in particular an object having an elevated temperature, in a power transfer area of an inductive power transfer (IPT) system, the arrangement comprising: a primary side electric conductor assembly (3) of the IPT system for producing an electromagnetic field in order to transfer power and/or a secondary side receiving device (2) of the IPT system for receiving the electromagnetic field and for producing an electric current by magnetic induction and an optical waveguide (101) being arranged in the area in which the electromagnetic field propagates during operation of the IPT system and being adapted to guide light within the optical waveguide (101) through the area.
