Strongly anti-misalignment wireless power transmission system based on dsfs-dd coil

Abstract

This invention relates to the field of wireless power transfer technology, specifically disclosing a strong offset-resistant wireless power transfer system based on DSFS-DD coils. This system proposes a novel magnetic coupling mechanism with strong offset resistance. The transmitting coil of this coupling mechanism consists of two forward-series flat solenoid coils (DSFS), and the receiving coil consists of a set of DD coils. The two forward-series flat solenoid coils at the transmitting end eliminate the mutual inductance zero point in the direction perpendicular to the centerline of the DD-type coupling mechanism, while simultaneously improving the offset resistance performance of the flat solenoid coupling mechanism parallel to the centerline. The system achieves offset resistance through the inherent characteristics of the coupling mechanism itself, eliminating the need for communication and complex control strategies, requiring no topology optimization, and reducing system reactive power loss. Simulation experiments verify the strong offset resistance characteristics of the proposed coupling mechanism.
