A New Design Methodology for a 300 kW, Low Flux Density, Large Air-Gap, On-Line Wireless Power Transfer System

초록

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 % coilto-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.
