Abstract: A power control of a wireless charging inverter is provided. Communication is performed between a driving vehicle and an inverter used for wireless charging of a vehicle. Using the location information of the driving vehicle, the time for the driving vehicle to enter the power supply line and the expected time to leave the power supply line are predicted. The power of the inverter is controlled by using the predicted enter and exit time information of the driving vehicle.

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.
