Power transfer system

Power transfer system comprising a transfer pick-up circuit for inductively picking up power from a cable carrying an alternating supply current. The power transfer system comprises a first circuit comprising the secondary winding of a transformer for providing an inductive coupling to the cable and a first capacitive module connected in parallel to the transformer. The transfer pick-up circuit further comprises a second circuit connected in parallel to the first circuit and comprises a second inductive module and means to transfer power to the load, the means being in series with the second inductive module.
