Research on Compensation Network of Wireless Charging System for Electric Vehicles

Electric vehicle wireless charging technology has attracted widespread attention in the industry in recent years. The technology has the advantages of flexibility, operation safety and low maintenance cost, and is one of the development trends of electric vehicle charging and replacing technology in the future. This paper theoretically analyzes the compensation network topology of wireless charging systems, and summarizes the current research status of wireless charging system compensation network topology. The explicit limits of the two modes of magnetic coupling and magnetic resonance are theoretically derived and verified by simulation calculations and physical experiments. At the same time, this paper proposes a method to determine the compensation boundary of various wireless charging systems based on simulation calculation and physical experiment. Therefore, in practical engineering applications, an appropriate working mode can be selected according to a specific application scenario.
