Wireless Power Transfer (WPT) has been the main research topic for decades ever since the first successful experiment done by Nikola Tesla in 1899. Nikola Tesla’s experiment focused on the transmission of power wirelessly through 2 mutually coupled inductor coils. The experiment enabled power transfer over short distances without any usage of cables or wires. Due to his success, WPT became a well-known phenomenon in the research field. In the 21st century, technology has advanced at a rapid speed and our daily lives are affected by its changes. Now, the standardization is to eliminate the usage of cables and turn to wireless power transmission through near-field or far-field techniques. This project is focused on the near-field techniques such as Standard Inductive Coupling (SIC) and Resonant Inductive Coupling (RIC), which are the two commonly used methods in WPT systems. Therefore, this project aims to design a suitable WPT system for Charging using RIC. Literature review on key aspects such as WPT systems using near-field techniques such as SIC & RIC, and Resonant DC-DC converters will be covered. This project will show how the author designs a WPT system with its design specifications derived from formulas and a simulation of the WPT system is showcased, and simulation results will be discussed.
