1. An inductive power transfer (IPT) pick-up circuit for receiving power from a primary conductor at a selected operating frequency, the circuit comprising:

  • a pick-up coil and a compensation capacitor;

    a switch controllable between an operable state and an inoperable state;

    a plurality of additional reactive elements whereby when the switch is in one of the operable or inoperable states the additional reactive elements are resonant at the selected operating frequency to substantially reduce or prevent power being supplied to an output of the pick-up circuit.
