DE 102009012786 A1 UPAB: 20101014 NOVELTY - The method involves applying base-high frequency (HF)-alternating current (AC) voltage to a metallic conductive carrier (14) at locations (20, 21). A tapped voltage is tapped at a surface of the carrier at locations (24, 25), which lie between the former locations. A frequency of the base-HF-AC voltage is selected such that an impedance of the carrier is increased using skin effects and/or self induction in an area for reducing current through a driver unit (15) e.g. HF-AC generator, and the carrier and for producing power for operating a load (14). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for supplying energy to a load. USE - Method for supplying energy to a load such as a sensor e.g. proximity sensor, and an actuator (all claimed), which is used for process automation in an industry and for building automation. Can also be used for automotive, structure monitoring, micromanipulator and microrobot applications. ADVANTAGE - The method permits change of positions of the load on the metallic conductive carrier in simple manner, supplies energy to multiple loads using a single mains-operated unit with high performance, and allows the load to be durably operated. The method avoids occurrence of short-circuits at the carrier
