The optimal design of high-powered power supply modules for wireless power transferred train

摘要

In this paper, the wireless power transfer technology is applied to the high-powered train system. Through applying wireless power transfer technology, many defects of original train system (wired power transfer) can be overcome. The optimal design of power supply module for wireless power transfer system is required to make a 100kW power supply. Three approaches for deciding optimal design of power supply module are discussed. Three approaches are on about induced voltage of pick-up modules in various size of power supply, heat generation due to the magnetic flux from primary coil and types of the power supplying cables. Coupled simulations about magnetic-heat transfer and electrical experiments are conducted.
