1. A circuit arrangement of an electric vehicle for inductive power transfer to the vehicle, the circuit arrangement comprising:
a pick-up arrangement for receiving a magnetic field and for generating an output voltage, and at least one variable compensating arrangement, wherein the variable compensating arrangement comprises a capacitive element, wherein:
the variable compensating arrangement further comprises a first switching element and a second switching element, wherein the first switching element and the second switching element are connected in series, wherein the series connection of the first and the second switching element is connected in parallel to the capacitive element of the variable compensating arrangement; and
the circuit arrangement comprises at least one current sensing means for sensing a phase current of the circuit arrangement, wherein switching times of the first and the second switching element are controllable depending on the phase current.
