Design and optimisation of a wireless power transfer system for satellite application

The analysis and design of wireless power transmission coils for satellite on-board application are presented. Firstly, application background and design constrain are presented. Different factors affecting the coupling coefficient are analysed, and transmission cores fitting satellite application are designed and optimised. To reduce magnetic flux leakage and to improve transmission efficiency, ways to reduce magnetic flux leakage are analysed. According to the requirement of the system, suitable leakage reduction design is chosen, and different materials are simulated. Combining optimised transmission core design and magnetic flux leakage reduction design, a model fitting in required application is presented and simulated. Result shows the fitness of application requirement.
