“…The cross coupling and leakage impedance, Z cross and Z leak can be neglected when the distance between the transmitter and receiver is smaller than 25 mm [27]. At this distance the parasitic impedances are significantly larger than the main impedance Z main , and so are Z tr and Z rcv significantly larger than Z m .…”

“…Therefore, further research is needed into the losses in the coupler. This will give a better estimation of coupling and system efficiency [ 107 , 156 , 157 ]. Technologies and developments for charging EVs and robots are another important area of research, such as dynamic wireless power transfer (DWPT) and multiple phase WPT [ 158 ].…”

Wireless power transfer provides a most convenient solution to charge devices remotely and without contacts. R&D has advanced the capabilities, variety, and maturity of solutions greatly in recent years. This survey provides a comprehensive overview of the state of the art on different technological concepts, including electromagnetic coupled and uncoupled systems and acoustic technologies. Solutions to transfer mW to MW of power, over distances ranging from millimeters to kilometers, and exploiting wave concepts from kHz to THz, are covered. It is an attractive charging option for many existing applications and moreover opens new opportunities. Various technologies are proposed to provide wireless power to these devices. The main challenges reside in the efficiency and range of the transfer. We highlight innovation in beamforming and UV-assisted approaches. Of particular interest for designers is the discussion of implementation and operational aspects, standards, and safety relating to regulations. A high-level catalog of potential applications maps these to adequate technological options for wireless power transfer.
