TL;DR: In this article, a multilevel gate driver is proposed to mitigate the coupling noise effectively, which adds a capacitor, an auxiliary mosfet, a Zener diode, and two resistors to regulate the turn-off voltage bias.

TL;DR: This article presents a system-level model for WPT applications, including all the critical interior blocks, such as power amplifier, transmitter coil, receiver coil, matching networks, and rectifier, and an accurate characterization method is proposed to obtain the rectifier impedance as a realistic load condition.

TL;DR: In this article, a method for adjusting the effective permeability of the ferrite blocks in the standard model, to tune the self-inductance of the coils as well as the coupling coefficient was proposed.

TL;DR: In this paper, the authors introduced the method of tuning the coil's inductance and coupling coefficient by adjusting the effective permeability of the ferrite blocks, and obtained reasonable electrical parameters; inductance of ground-assembly coil, inductances of vehicle assembly coil, and coupling coefficients.

TL;DR: In this paper, the root cause of desense noise is identified as the non-ideal electrical connection between the metal chassis and the USB receptacle shell where it is installed.
