New approach to wireless power transfer for electrical vehicles battery charging is discussed in a paper. The system of power transfer consists of generating unit with VSWR meter, two electromagnetic structures, and rectifying unit. Electromagnetic structure which is represented as microstrip device does not emit electromagnetic energy at its stand alone position. When electromagnetic structures approach each other ones are transformed into alone directional coupler; and effective power transfer takes place. System simulation in AWR design environment was carried out at different mutual arrangements of microstrip units. It was shown the power loss did not exceed 1 dB in a wide range between system parts and its mutual arrangements. Experimental model of system for power transfer was made and experimental study was carried out. Experimental and simulation results are well agreed. The reasonable system size and weight are well situated for its use for battery charging of electrical vehicle.
