Abstract

Wireless Power Transfer (WPT) solves the friction problem of contact slip rings by its non-contacting characteristics. If WPT is to be applied in spacecraft, the WPT system must be designed for fault tolerance and redundancy to improve the stability and reliability of the system. Currently, fault-tolerant designs in WPT systems focus on anti-offset ability. This paper designs the high-reliability WPT system with redundancy, proposes the fault-tolerant control method for the disconnection fault of the transmitting coil, a parameter-consistent multi-coil magnetic coupling mechanism, and a multi-coil circuit decoupling method based on compensation capacitors are proposed for the effect of coupling between multiple coils. The parametric consistency of the novel coils and the decoupling process of multiple coils are experimentally verified.
