Abstract-Wireless power transfer (WPT) could revolutionize global transportation and accelerate growth in the Electric Vehicle (EV) market, offering an attractive alternative to cabled charging. Coil misalignment is inevitable due to driver parking behaviour and has a detrimental effect on power transfer efficiency (PTE). This paper proposes a novel coil design and adaptive hardware to improve PTE in magnetic resonant coupling WPT and mitigate coil misalignment, a crucial roadblock in its acceptance. The new design was verified using ADS, providing a good match to theoretical analysis. Custom designed receiver and transmitter circuitry was used to simulate vehicle and parking bay conditions and obtain PTE data in a small-scale setup. Experimental results showed that PTE can be improved by 30% at the array's centre, and an impressive 90% when misaligned by 3/4 of the arrays radius. The proposed novel coil array achieves overall higher PTE compared to the benchmark single coil design.

High frequency two-plate capacitive wireless power transfer system

“…The inductive WPT system has the EMI issue, electromagnetic radiation is proven to have adverse effects on the environment and health [3] of the people exposed to the radiation, therefore shielding is required. The shielding and use of magnetics makes the cost of such system extremely high [4]. This motivates researchers to find alternative forms of wireless energy transfer.…”

“…The WPT system should comply with the relevant safety standards for the magnetic field. WPT technology finds its application in electrical vehicles [4][5][6][7][8][9], electronic gadgets charging [10], medical applications [11] and in many other applications. A promising WPT application is dynamic charging of electric vehicles [12] by placing WPT transceiver side under the road.…”

Research on wireless power transfer system for Torpedo autonomous underwater vehicles

“…Since Tesla coils were invented by Nikola Tesla in 1889, 1 the wireless power transfer (WPT) has been developing and it enters into a new development period since researchers at MIT proposed strongly coupled magnetic resonance. 2 For the advantage of being safe and convenient, the WPT attracts much attention and shows great potential in the future and it has been widely researched in the field of electric vehicles (EVs), 3,4 electronics, 5 implantable devices, 6,7 and special applications. 8 Due to the relatively wide transmission distance and high efficiency, magnetic resonant coupling wireless power transfer (MRWPT) is one of the appealing WPT approaches (Figure 1).…”
