Development of Static Inverter for European Electric Railway

유럽형 전동차용 보조전원장치 개발

The static inverter is mainly used to provide with the electric power of various loads in the train. In the recent european projects, the specification of static inverter become harder, and many additional service function is expected. It takes long time and high cost to develope a static inverter with these high performances and additional function. But, these are became general demands for static inverter in the many projects from now on. The APSE(Auxiliary Power Supply Equipment) is a static inverter of high performance to satisfy the severe specification and various service function following these tendency for Athens project In this paper, the specification of APSE and various service functions are introduced to look about current tendencies of static inverter.
