Transfer Systems: Compensation Networks, Soft-Switching Techniques, and Future Trends

Abstract

This article carefully addressed the development of Wireless Energy transmission (WPT) systems using different types of compensation networks (CN), as well as the various soft-switching schemes employed. The major conclusions of the study are that suitable CN designs facilitate a feasible approach for power transmission when the operating conditions allow an optimal resonant match, which is true of several forms of CNs including those based on Inductor-Capacitor-Capacitor (LCC), SSCN, etc., maximizing the power transfer capability. Softswitching techniques help reduce reactive power loss and stray loss. They also lower switching loss, electromagnetic interference (EMI), and thermal stress. Reducing these losses and stresses improves system reliability, thereby indirectly extending the operating time. In other words, the fusion will allow us to have better performance on power transfer rate, less energy waste, greater work stability; It’s not relevant to coupling state nor loading situations for real-world wireless power transmission.
