High-Power Wireless Power Transfer (WPT) System Using Series-Series (SS) Topology

Due to its various uses, wireless power transfer (WPT) technology has recently become one of the most significant study areas. This technology is being pushed into new fields of study and research as more and more innovative thoughts and ideas is emerging daily. WPT technology has undergone significant advancements due to research and development, both in low- and high-power applications. Electric vehicles are charged employing high-power sources. Therefore, it is always difficult to charge electric vehicles in a way that is secure, effective, and safe. Most of these difficulties can be overcome through wireless power transfer (WPT). WPT transformers are operated at high frequencies to provide significant amounts of power with excellent efficiency for electric vehicle charging stations. High-power WPT systems often need specialized high-frequency voltage source inverters. For high-power WPT applications, a high-frequency voltage source resonant inverter employing SS topology has been discussed in this study. The proposed WPT transformer design has been optimized using Ansys Maxwell and a 5.5 kW WPT system has been validated using Ansys Simplorer circuit simulation.
