Wirelessly transferring power is not something new to us, and over the years, it has become more prominent. Initially, wirelessly transferring power may sound impossible, but this magical way of transferring power without using any cords can help us change our traditional way of charging electronic devices, implanted medical devices, electrical vehicles (EVs), unmanned aerial vehicles (UAVs), and so forth. [1] With the remarkable flexibility, movability, and position-free characteristics of WPT, this method of power transfer can be utilized in conditions where conventional wires are inconvenient, hazardous, or impossible to deploy. [2] When we talk about Wireless Power Transfer (WPT), we cannot mention it without referring to Nikola Tesla, the pioneer scientist/engineer who explored WPT using a coupled alternating magnetic field. Nikola Tesla's research on WPT was the most impactful and recognized up to this date. [3] Due to environmental concerns, EVs have gained popularity over the years as they produce significantly lower emissions of greenhouse gases and other pollutants compared to gasoline-powered vehicles. For EVs, there are two main methods of charging the battery within the vehicle: using a wired cord or wirelessly. With the advancement of technology, WPT has gained popularity for charging EVs due to the advantages it offers over conventional wired systems in terms of the convenience and safety it provides. Therefore, the project aims to develop both mathematical and simulation models and provide studies on the maximum energy efficiency for such a WPT system.
