摘要： Disclosed are a primary coil unit having four coils independently controllable and a pickup coil unit having four coils also independently controllable. The proposed power transfer system and the proposed power pickup system can satisfy standard compatibility and improve the efficiency of wireless power transmission. The power transfer device is compatible with various types of conventional power pickup systems and capable of expanding compatibility with a new power pickup system to be developed in future by changing the power transfer magnetic flux pattern. The power pickup device is compatible with various types of conventional power transfer systems and capable of expanding compatibility with a power transfer system to be developed in future. The system including both the power transfer device and the power pickup device is more robust against a deviation.
