Abstract

Transmitter component of high power inductive wireless transmission systems for electric busses and trucks should be embedded in the road to ensure a free circulation of vehicles and to ensure a good mechanical resistance of the pavement, in the charging region, similar to the rest of the road. In such application, ferrites cannot be envisaged as magnetic flux concentrators due to their fragility. An adequate solution to replace the ferrites consists in using magnetic concrete as magnetic field concentrator for wireless inductive transmission system. This solution is analyzed in this paper and used for an MIMO (Multiple-Input-Multiple-Output) inductive wireless power system based on Double-D structure coils, for a transferred power of 125 kW, corresponding to the standard project SAE J2954-2, sufficient for an electric bus for 50 persons. The Finite Element analysis carried out in the paper has the objective of determining the useful and parasitic magnetic coupling parameters of the proposed inductive power transfer system

大功率无线系统的Mimo电感耦合

用于电动公交车和卡车的高功率感应无线传输系统的发射机组件应嵌入道路中，以确保车辆的自由流通，并确保路面的良好机械阻力，在充电区域，类似于道路的其余部分。在这种应用中，铁氧体由于其易碎性而不能设想为磁通集中器。用磁性混凝土作为无线感应传输系统的磁场集中器是取代铁氧体的一种适当的解决方案。本文对该方案进行了分析，并将其应用于基于双d结构线圈的MIMO(多输入多输出)感应无线电源系统，传输功率为125 kW，符合SAE J2954-2标准项目，足够50人的电动公交车使用。本文进行的有限元分析的目的是确定所提出的感应功率传输系统的有用和寄生磁耦合参数
