Abstract
A multiphase power supply apparatus for wireless power transmission and a control method thereof are disclosed. The multiphase power supply apparatus includes two power supply coils and coupling coefficient between the power supply coils is below a predetermined value. When it is determined that a deviation in alignment with the corresponding pickup has occurred, the phase difference between the inverters is adjusted. When adjusted to the optimum phase difference, the output of the pickup coils becomes uniform, even if there is a deviation in the alignment between the power supply apparatus and the pickup.
