Summary: This article proposes a fast and real-time mutual inductance estimation method for drone in-flight wireless charging systems. The critical challenge for in-flight wireless charging systems is to track variations of mutual inductance caused by continuously changed misalignments between coupling coils, which is rarely explored in previous studies. The proposed rotating-coordinate-based estimation method effectively enhances the rapidity and simplicity of the estimation process, while eliminating wireless communication links. With the features of accuracy, rapidity, and real-time performance, it can be an ideal solution for drone in-flight wireless charging systems.

Summary: This paper discusses resonant systems used with the main resonator present on NMR or MRI instruments. The aim is to improve spatial localization and signal to noise ratio using an additional smaller coil. Two practical devices are presented, one with passive decoupling and another with strong coupling. The behavior of the coil system is examined with regard to the amplitude of B-1. Technical hints for achieving optimal energy transfer are also discussed.

Summary: This article proposes a magnetic integrated method for the coupler of the electric vehicle dynamic wireless charging system to suppress power fluctuation. The method replaces the original single mutual inductance with the mutual inductance difference between the two reverse series transmitting coils and the receiving coil to determine the power transmission, which suppresses output power fluctuation. Additionally, the secondary-side integrated inductor coil replaces the bulky external compensation inductor in the LCC resonance compensation network and achieves better zero-voltage switching conditions.
