## 1 Introduction  
The fourth or fifth industrial revolution is the future of our society, and the requirement for wirelessly charging the batteries of electronic devices has motivated power electronic engineers to find innovative ways to overcome the future charging infrastructure problem [1]. The electronic product designers and engineers previously experienced power challenges in the form of continuously supplying power, recharging batteries, optimizing the location of sensors, and dealing with rotating and moving joints in electronic machinery. Although these challenges remain unresolved, new demands that arise from the increased use of mobile devices and the operation of these devices in dirty or wet environments mean that designers require new approaches for supplying power to electronic equipment [2]. The vision of wireless power transfer (WPT) provides a practical resolution to the challenges often experienced with the incessant contact-charging or wired cable charging of mobile device batteries. The conjecture and evidence of WPT originated in the early 19 th century. The idea of transferring power wirelessly was initially suggested by [PERSON] in 1891 with his Tesla coil invention [3]. The theory of electromagnetism states that electromagnetic waves move at the speed of light and that light is a wave [4]. Power can be wirelessly transmitted up to certain distances using a transmitter coil and a receiver coil. This technique can make a dramatic change in the field of electrical engineering in the nearest future. It can cause breakthrough innovation or disruptive innovation by eliminating the use of physical wires, different cables, connectors, and power cords that are currently pervasively used to transmit power up to large distances [5]. In addition, the magnetic resonance coupling (MRC) would be a practical resolution for wirelessly charging the batteries of pacemakers fitted inside the body of heart patients to eliminate the endless replacement of pacemaker batteries [6]. WPT is trending in the medical field [7] through implementing a wireless charging method for active implantable medical devices (AIMDs). These devices include mechanical pumps that are responsible for pumping blood within the body of a patient, a Doppler flow meter that monitors the flow of blood for signs of clotting, and endoscopic capsules that detect or diagnose health risks related to the gastrointestinal (GI) tract [8]. MRC can be used for different real-life applications like charging the batteries of mobile devices, including the batteries of laptops, iPods, aviation devices, wind turbines, and automation systems [8]. The method of charging the batteries of mobile devices will be made more convenient when WPT is finally accomplished, because the method will eliminate the necessity to regularly plug a cord into an electrical outlet [9; 10; 11]. In addition, as power can be transferred constantly to the batteries of mobile devices, the battery size can be reduced significantly. Moreover, the danger of being electrocuted because of the wear and tear of old power cords will be avoided completely. This is because the process of handling a power cord would not be necessary, thus making the charging process safer. The WPT system must satisfy three essential conditions of high efficiency, large air gaps, and high power in order to achieve wireless charging [12]. There are a few challenges that need to be considered when utilizing the WPT system to charge the batteries of electronic devices. They include an interruption to the frequency of less than 150 kHz, WPT charging points, and appropriate charging frequencies for the various devices. These should be considered with the charging expectations of the WPT system [13]. Extensive research has been conducted on WPT used for charging electric vehicles. The agglutination of WPT with MRC was used to charge the wheel motion in electric vehicles [14].
