<p>An arrangement adapted for receiving an electromagnetic field, for producing electric energy from the electromagnetic field by induction and for providing a load 205, particularly a rail vehicle, with the electric energy. The arrangement comprises at least one phase line 1a, 2a, 3a comprising an inductance L71, L72, L73 and a capacitance C71, C72, C73 and a rectifier 203 connected to the at least one phase line. The capacitance is arranged and used to optimize a phase shift between the voltage induced by the electromagnetic field and the current produced by the voltage while electric energy is transferred to the load. The capacitance comprises at least two capacitors 371, 381, 382, 383, 384 and at least one of the capacitors is switchable and is connected to the phase line via a switch 385, 383, 387, 388. A control device 397 is provided, connected to the switch and adapted to switch on or switch off the at least one switchable capacitor so that the capacitance, and thereby the phase shift is modified.</p> |
