Abstract
An inductive power transfer (IPT) pick-up circuit for receiving power from a primary conductor has a pick-up coil (L2) and a compensation capacitor (C2) so that the pick-up coil (L2) may be resonant at the system operating frequency a switch (S1, S2), and a plurality of reactive elements (L3, C3) whereby when the switch is in one of an on state or an off state the additional reactive elements (L3, C3) are resonant at the operating frequency to reduce power being supplied to an output of the pick-up circuit.
