The invention relates to a wireless electric energy transmission system based on a multi-turn coil. The wireless electric energy transmission system is characterized by comprising a power supply, a transmitting coil, a resonance circuit and an H-bridge converter; according to the wireless power transmission system with the three-coil structure, the source coil does not occupy the space between the transmitting coil and the receiving coil, and the source impedance becomes smaller due to the existence of the source coil, so that the efficiency of the wireless power transmission system can be effectively improved; the wireless power transmission system with the three-coil structure has the advantage that the load change intensity near the maximum efficiency point of the system can be improved; the wound composite magnetic coupling resonant wireless power transmission coil adopts a transmission line with a multi-layer composite structure, so that a transmitting coil and an exciting coil or a receiving coil and a load coil are compounded into a whole, and an air gap between the transmitting coil and the exciting coil or between the receiving coil and the load coil can be reduced to the greatest extent; and the mutual inductance or coupling coefficient between the two can be maximized, and the energy loss in the transmission process is reduced to the minimum.
