“…Wireless power transfer with loosely coupled coils is a promising solution for delivering power to a battery in a variety of applications [10,11]. In such a system, the coil embedded in a receiving device picks up the energy transferred through the magnetic field induced by the transmitter coil; thus, contactless charging is achieved.…”

WPT system performances highly depend on the misalignment scenarios of the transmitter or the receiver coil. In this contribution, the authors analyze the effect of the misalignment influencing factors of the integrated WPT-PLC system receiving coil on the system performances. The simulations and experimental analysis are based on power efficiency and channel capacity metrics. The simulations are performed using finite element calculations in COMSOL Multiphysics and Advanced Design System (ADS) from Keysight technology. By analyzing the results, maximum transferred power is reached under resonance conditions. For instance, the calculated efficiencies versus the misalignment cases of the WPT-PLC system varies (η = 86% to 60%) when d = [3 cm to 7 cm], s = [3 cm to 9 cm], and for a tilt angle θ ≤ 20 deg, while the optimal data rate C(bps) is achieved while appealing different data access points and under reasonable SNR value.

Abstract-This paper presents a control process and frequency adjustment based on the Magnetic Core Reactor prototype. For the past decades, there has been significant development in the technologies used in Wireless Power Transfer systems. In the Wireless Power Transfer systems it is essential that the operating frequency of the primary circuit be equal to the resonant frequency of the secondary circuit so there is the maximum energy transfer. The Magnetic Core Reactor allows controlling of the frequencies on both sides of the transmission and reception circuits. In addition, the assembly diagrams and test results are presented.

This paper deals with Wireless Power Transmission (WPT), and its main futuristic application, Space-based Solar Power (SSP). In the first part, the decisive role played by physicist Nikola TESLA in the development of electricity industry, his major concrete contributions, and his prophetic intuitions concerning wireless power are presented. The basics of the physics of the domain are also recalled. In the second part, the main experiments led until now in the domain of WPT are presented, as well as the different technical approaches available in the field. A few current applications of WPT at low power are briefly described. In the third part, a survey of the actual state of SSP projects is presented.
