There is described a wireless power transfer system utilizing a new excitation-quadrature-quadrature transmitter pad which includes one excitation coil and at least two decoupled quadrature auxiliary coils. A described resonant tank design method is proposed for constant-current charging and zero phase angle conditions. When there is a lateral misalignment in the receiver pad, the auxiliary coil that is better coupled with the receiver pad conducts more current than the more distant auxiliary coil does, reducing the leakage magnetic field in the surrounding area and/or improving transmission efficiency.
