A new design methodology for a 300 kW, low flux density, large air-gap, on-line wireless power transfer system

A high power on-line wireless power transfer system has been investigated intensively in recent years. However, no literature has focused on the design methodology of the high power on-line wireless power transfer system with low flux density, high efficiency, and high control stability. This paper proposed a new design methodology for a 300 kW, over 96%coil-to-coil efficiency, ICNIRP´s safety regulation compatible on-line wireless power transfer system. Using a finite element analysis and experimental results, the proposed design methodology has been evaluated.
