Research on Guideway Magnetically Coupled Mechanism for Dynamic Wireless Charging System

Wireless charging; Magnetic coupling mechanism; Guideway type

In recent years, as an important supplement to the wired charging method, the application field of wireless energy transmission technology has been expanding and has great development prospects. The magnetic coupling mechanism is one of the most important components of the entire wireless energy transmission system. In this paper, a kind of rail-type magnetic coupling mechanism of "work" type is designed based on the dynamic wireless charging system. The magnetic circuit model of the magnetic coupling mechanism is given, and the basic factors affecting its transmission characteristics are analyzed. The ANSYS electromagnetic simulation software is used. The "work" type rail-type magnetic coupling structure parameters are simulated to obtain the relationship between the coupling coefficient and the structural parameters. At the same time, the corresponding coils are actually wound and matched with appropriate capacitors. At the same time, the SS-type simulation model is built by Matlab to verify the resonance effect, and at the same time The experimental prototype was tested and verified.
