| Abstract(in English) | Litz copper wires are generally used in wireless power transmission coils for electric vehicles to reduce high-frequency losses. However, the production of Litz wire is expensive. Herein, a copper plate coil is proposed, which can be manufactured at a low cost. To overcome the issues of high copper loss and low transmission efficiency, a magnetic flux path control technique is also proposed. Using this technology in the copper plate coil, AC resistance is decreased from 187.4 to 80.2 mΩ. Furthermore, the transmission efficiency of the copper litz wire is 97.29%, the analysis value of the transmission efficiency of the copper plate coil using the magnetic flux path control technology is 97.54%, and equivalent transmission efficiency is expected. Therefore, copper plate coils using magnetic flux path control technology that can be manufactured at low cost are useful. |
