주지된 바와 같이, 국내 산업선을 운행중인 구형 전기기관차의 경우 사이리스터(Thyrister)를 주회로 스위칭 소자로 사용하고 위상제어 정류방식을 사용하여 견인회로를 구성하고 있다. As is well known, in the case of the old electric locomotives operating domestic industrial lines, thyrister is used as the main circuit switching element, and the traction circuit is constructed by using a phase controlled rectification method.

하지만 제어방식의 특성상 입력측의 역률이 매우 낮아 변전소의 부담이 크며 직류전동기를 사용하므로 견인전동기의 잦은 고장이 문제점으로 대두되고 있다.However, due to the characteristics of the control method, the input power factor is very low, so the load on the substation is large, and since a direct current motor is used, frequent failures of the traction motor are emerging as problems.

이에 대한 개선방안으로 도입된 신형 전기기관차는 주회로 스위칭 소자로서 GTO(Gate Turn-off)사이리스터를 채용하고 VVVF(Variable Voltage Variable Frequency) 제어방식에 의한 교류 유도전동기를 구동함으로써 최고속도 150 [km/h]의 고속운전이 가능하게 되었다.The new electric locomotive introduced as an improvement measure adopts GTO (Gate Turn-off) thyristor as the main circuit switching element and drives AC induction motor by VVVF (Variable Voltage Variable Frequency) control method. h] can be operated at high speed.

또한, 전력 스택은 긴급하게 착탈하는 경우, 접속 신뢰도를 담보하지 못한 상태에서 성급한 작동이 이루어지는 경우가 있고, 그럴 경우 안전사고에 심각한 우려가 예상된다는 문제가 있었다.In addition, when the power stack is urgently attached and detached, there is a problem that premature operation is performed without guaranteeing connection reliability, in which case a serious concern for a safety accident is expected.
