A Study On Full Load Test of IGBT Type Propulsion System for Electric Railway in SMG 6 Line

전동차용 IGBT형 추진제어장치의 6호선 본선 만차 시험에 관한 연구

This paper describes the full load test results of IGBT VVVF inverter for the railway propulsion system. The 1,650kVA IGBT VVVF inverter has been developed. Therefore, the field test is performed in SMG 6 Line to confirm its the reliability and performance. The train consists of 4M4T(4 Motor car 4 Trailer Car) and the electrical equipment for field test are as follows VVVF inverter 4 sets, 16 traction motors and 2 SIVs. The propulsion system is composed with IC4M(1-Controller 4-Motors). The results of propulsion system which have the excellent acceleration/deceleration and the jerk characteristics as well as starting ability on slope are taken through the field test.
