“…Nowadays, WPT technologies are attracting widespread interest in fields such as home electronics, medical implants, EV's and the aerospace industry. WPT technologies can be categorised into three groups, namely inductive coupling, magnetic resonant coupling (MRC), and electromagnetic radiation-based WPT [2]. MRC-WPT is advantageous with respect to its high safety and longer transmission distance [3].…”

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.

Wireless Power Transfer (WPT) has been widely studied for decades by using the Series Resonance (SR). Most of the resonant frequency is in a range of 200 kHz -13.56 MHz. Additionally, a pure resistive load is commonly adopted for simplifying a design under Impedance Matching (IM) condition. However, there are usual problems presented in the past studies. For example, i) common electrical loads are complex, so the SR structures are difficult to be designed for achieving the IM condition, ii) the resonant frequency in this range causes several problems, e.g. the tissue absorption on humans, electromagnetic interference, etc. In this paper, we propose the method to design the Parallel Resonance (PR) using an optimal primary capacitance for achieving the IM condition, which can operate at a low frequency, as 15 kHz, at a complex load.
