2D THE APPARATUS OF IN-DIRECT FED WIRELESS POWER TRANSFER USING COMPLANATION OF LOOP AND COIL

摘要

In the present invention, since resonance coils and loops constituting a conventional wireless power transmission system by a self-resonance method are formed in 3D solid shapes of X axis, Y axis, and Z axis, they are bulky and heavy, In the case of a device having a variable position due to transmission of electric power by radio using an electromagnetic resonance method, there is a problem that the wireless power wavelength is unstable due to the change of the resonance frequency and the impedance, The resonance coil and the resonance loop can be formed into a flattened shape of the annular spiral having the 2D structure of the X axis and the Y axis so that the wireless power can be transmitted at a short distance of 5 cm to 50 cm at a resonance frequency of 1 to 10 MHz, It can reduce volume and weight by 80% and is made of nylon, cotton, polyester, polypropylene, acrylate It is possible to fabricate a reciprocal substrate and it is possible to form a resonator pattern on both sides with good flexibility and it is possible to provide a transmission efficiency of 70% compared with the conventional one through a stable inductance value and a capacitor value. The present invention provides a smart 2D type self resonance wireless power transmission / reception device in which a resonance coil and a resonance loop are flattened on one same plane that can be widely applied to IT devices, clothes, and medical fields.;
