The high Q-factor coil with negative impedance converter (NIC) is investigated. The NIC leads to the enhanced transmission efficiency at a long distance for wireless power transfer (WPT) with magnetic resonance coupling method. The negative resistance generated by the NIC reduces the resistance of the coil. The coils were considered for the practical application such as effects of the ferrite and...
Proper selection of magnetic material is very important to maximize the power transfer efficiency (PTE) in case of the conductor in the receiving coil. The effects of the relative permeability and loss tangent of the magnetic material are investigated. A relatively low complex permeability ensures a high efficiency in wireless power transfer system (WPT) at 6.78 MHz. To maximize the PTE, the properties...
Compact coil is designed at 6.78 MHz for wireless power transfer (WPT) system. The proposed coil is optimized by adjusting the gap between wires, scaling factor, and the number of turns to achieve high quality factor (Q-factor), and its Q-factor is 263. The Q-factor of the proposed coil exhibits 1.21 times higher than conventional coil. The coil is made on thin substrate with a low relative permittivity...
