In an Inductive Power Transfer (IPT) system, the magnetic design of the primary and secondary pads is an important factor that determines the power transfer capability. This paper proposes a DD2Q power receiver coil set, a novel three coil magnetic pad that comprises a classical DD winding and two additional quadrature windings placed at the secondary side (referred to as 2Q). The DD2Q coil set achieves tolerance to larger lateral displacements and rotational displacements than conventional DD pads. A 100 W contactless energy transmission system using the proposed transformer is tested.
