A Study on Performance Characteristics for Auxiliary Converter of Korean High Speed Train

한국형 고속열차 보조컨버터 성능 특성에 관한 연구

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 performance evaluation of the on-board devices is crucial. Because temperature bas a serious effect on failures of the components of the devices, its measurement is the first step for good management. In this study, we described performance characteristics of domestic auxiliary block developed through G7 project. We measured the performances of auxiliary block during test running by the developed on-line measurement system. After we save the input real-time data from each signal of Korean High Speed Train through the network line, we can acquire necessary information through Post-Processing program. We verify the auxiliary converter characteristics of Korean High Speed Train by this system.
