OPERATING AN INDUCTIVE ENERGY RECEIVER

Title:

OPERATING AN INDUCTIVE ENERGY RECEIVER

Document Type and Number:

WIPO Patent Application WO/2012/010649

Kind Code:

A3

Abstract:

The invention relates to an arrangement adapted for receiving an electromagnetic field, for producing electric energy from the electromagnetic field by induction and for providing a load (205) with the electric energy, in particular for providing a rail vehicle with energy. The arrangement comprises: (a) at least one phase line (1a, 2a, 3a) comprising an inductance (L71, L72, L73) and a capacitance (C71, C72, C73), wherein the capacitance (C71, C72, C73) is arranged and used to optimize a phase shift between the voltage which is induced by the electromagnetic field and the current which is produced by the voltage while electric energy is transferred to the load (205), (b) a rectifier (203) which is connected to the at least one phase line (1a, 2a, 3a), wherein: (c) the capacitance (C71, C72, C73) comprises at least two capacitors (371, 381, 382, 383, 384), (d) at least one (381, 382, 383, 384) of the capacitors (371, 381, 382, 383, 384) is switchable and is connected to the phase line (1 a, 2a, 3a) via a switch (385, 386, 387, 388) and (e) the arrangement comprises a control device (397) which is connected to the switch (385, 386, 387, 388) and which is adapted to switch on or switch off the at least one switchable capacitor (381, 382, 383, 384) so that the capacitance is modified, thereby the phase shift is modified and thereby an efficiency of the arrangement is improved.
