Disclosed are a primary coil unit of a new type having four coils which are independently controllable and a pickup coil unit having four coils which are independently controllable. There are a proposed power transfer system and a proposed power pickup system which can satisfy standard compatibility and improve the efficiency of wireless power transmission by a power transfer device and a power pickup device. 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 apower transfer system to be developed in future. It has been confirmed that if the power transfer device and the power pickup device are combined to construct a single wireless power transfer system,the effects are superimposed so that the system is more robust against a deviation.
