Development and Revenue Service of Propulsion System Using Integrated Stack(PEM) and Heat Pipe

일체형 스택(PEM) 및 냉각장치를 적용한 전동차 추진제어장치 개발 및 상용화

Power semiconductor which is adapted in the rolling stock has a high practicality for capacity of high voltage and high speed switching. but it has a trouble of fever cause of high speed On, Off switching loss and the operating junction temperature is limited to $150^{/circ}C$ because is made from the silicon for the foundation material. Therefore, it is important to find a way out of this trouble and must make the countermeasure. In this research, the caloric value of the integrated PEM is calculated to adapt the optimized heat pipe and the reliability of the heat pipe is demonstrated through the cooling performance test and vibration test.
