Abstract
© Published under licence by IOP Publishing Ltd. This paper presents the design, modelling and simulation of a wireless power transfer system with improved 3D spatial efficiency. It is shown that a rotational field driven by balanced magnetic coils carrying phase-shifted currents can achieve almost uniform efficiency in 3-D space. Both 2-coil and 3-coil transmitting systems are designed and studied. Effective mutual inductance is proposed to visualize the magnetic fields from a multiple transmitter system, and efficiency distributions are simulated. Different excitation modes including phase-shifted and non-phase-shifted currents are analysed and compared. The results provide an approach to the design and excitation of the 3D multiple-transmitting-coil system.
