It is essential to evaluate the harmonic characteristics of high speed train using power electronics equipments such as converter driven motor drives, battery chargers and auxiliary power supplies. The purpose of this study is to measure and analyze the harmonic characteristics of a Korean high speed train (KHST) prototype on the Seoul-Pusan conventional line. This paper presents the results of harmonics...
High-speed railway vehicle has many electric devices such as main transformer, motor block and traction motor. As the on-board electric devices determine the performances of vehicles, production of reliable devices is important. To keep the reliability of devices constant, management of temperature characteristics of the on-board devices is crucial. Because temperature has a serious effect on failures...
