Abstract

An arrangement for inductively transmitting energy for charging an energy storage device of a rail vehicle. A first induction element transfers energy to a second induction element. An inverter with an adjustable AC voltage frequency provides an AC voltage to the first induction element. A controller controls the AC voltage frequency of the inverter. A measuring device ascertains a power output value during the wireless energy transmission and transmits the value to the controller and the controller adjusts AC voltage frequency of the inverter downward from an upper threshold until a pre-specified power output value is set while energy is being transmitted. The first induction element is paired with a track for rail traffic. The system and a method are also described for inductively transmitting energy for charging an energy storage device of a rail vehicle.
