“…An indispensable stage in IPT circuits is the resonant tank, also known as resonant network, which is an electrical circuit designed with capacitors and inductors which is capable of storing electrical energy and oscillating when it is operating at the resonant frequency. The circuit has zero reactance during the resonance condition, allowing the maximum transfer of power from a power supply to an electrical load with high efficiency [12,13].…”

The main contribution of this paper is the inductive compensation of a wireless inductive power transmission circuit (IPT) with resonant open-loop inductive coupling. The variations in the coupling coefficient k due to the misalignment of the transmitter and receiver are compensated with only one auxiliary inductance in the primary of the inductive coupling. A low-power prototype was implemented with the following specifications: input voltage Vin = 27.5 V, output power Po = 10 W, switching frequency f = 500 kHz, output voltage Vo = 12 V, transmission distance d = 1.5 mm. Experimental results varying the distance “d” with several values of the compensation inductor demonstrate the feasibility of the proposal. An efficiency of 75.10% under nominal conditions was achieved. This proposal is a simple compensation topology for wireless chargers of cellular phones presenting small distances between the transmitter and receiver.

Implantable biomedical devices (IBMD) and biomedical sensors (BMS) enhance patients’ quality of life by monitoring vital signs, detecting diseases, and replacing malfunctioning organs. However, IBMDs and BMSs require battery power to operate, and they have limited battery life. Wireless power transfer (WPT) is one practical way to address this limitation. In this paper, the authors designed and implemented WPT‐based magnetic resonant coupling (MRC) using a spider‐web coil (SWC) (WPT–MRC–SWC) that supplies the proposed IBMD, including accelerometer sensors, the single‐chip microcontroller ATmega 328, and the nRF24L01 wireless protocol, with power. The WPT–MRC–SWC examines acceleration measurements on three knee‐joint axes (X, Y, and Z) in five different positions: sitting, standing, walking, lying down, and jogging. The SWC of transmitters and receivers (implanted) exhibits an operating frequency of 1.78 MHz with a series/parallel (S/P) configuration. The implanted system's data, transmitted outside the human body using nRF24L01, operates at 2.4 GHz. The results reveal that WPT provides 5 V at an air gap of 60 mm between the receiver and transmitter coils, indicating that it can run or charge IBMD batteries without failure. This study validates the effectiveness of the WPT–MRC–SWC by applying it to an actual application.

“…Therefore, in recent years, many countries have developed rapidly stratospheric solar-powered UAV. The Airbus Zephyr S completed 18 consecutive days of flight in 2021, China's Qimingxing-50 solarpowered UAV cruised at an altitude of more than 20,000 meters, and the Phasa-35 developed by Britain's BAE Systems and Prismatic can carry a mission payload of 15kg [1].…”
