摘要：
While many companies have launched various wireless chargers in mobile industries, conventional wireless power transfer (WPT) technologies are available only for a very short distance due to large attenuation of the magnetic fields. A magnetic beamforming WPT system achieves an enhanced power transfer efficiency (PTE) with a longer wireless charging distance than conventional WPT technologies by adjusting an input voltage source of a transmitter side regardless of a receiver side. However, a WPT system has to consider both the transmitter and receiver to achieve the maximum PTE. This paper presents a WPT system with a magnetic beamforming scheme applying load impedance optimization at the receiver side, whose PTE performance is verified via circuit simulation.
