Abstract: A wireless charging power supply and pick-up system during operation of electric vehicles and industrial equipment while operating is described. The withstand voltage problem on the power supply line was solved by the capacitor provided in the inverter, and the power supply line and common line arrangement. This makes it possible to extend the wireless power supply line and the economical problem of the wireless charging system is greatly improved. In the prior art, compatibility was maintained with various wireless charging pick-up pads installed in the vehicle by using a plurality of inverters. In this system, compatibility is satisfied at a lower cost by utilizing the relay present in the inverter. The EMI of the power supply line is reduced by maximizing the magnetic field cancellation effect by using the structure of the common line and the shielding tube.

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.

Abstract: Disclosed are a multi pickup coil for wireless charging of an electric vehicle such as an electric bus or an electric passenger car and industrial equipment while stopping or driving, and a pickup apparatus having the multi pickup coil. The multi pickup coil and the pickup apparatus provide high-capacity and high-efficiency wireless charging per unit area by performing performance enhancement through an optimal design in order to overcome the limitations of a circular pickup coil.
