Abstract

직류형 전철용 전력 공급 장치는 전력 공급 및 전력 재발전 동작을 수행하는 사이리스터 정류기와 사이리스터 정류기와 병렬이고 그 사이리스터 정류기보다 작은 직류 전압을 내는 정 전압 정류기를 포함한다.The DC power supply device includes a thyristor rectifier for performing power supply and power regeneration, and a constant voltage rectifier in parallel with the thyristor rectifier and outputting a DC voltage smaller than that of the thyristor rectifier.

그래서, 3차 정류기의 출력 전압이 0이 되더라도 전첨에 대한 전압은 보존되고 부족 전압 계전기의 작동으로 인한 전동차의 멈춤이 방지된다.Thus, even if the output voltage of the tertiary rectifier becomes zero, the voltage on the front end is preserved and the stopping of the electric vehicle due to the operation of the undervoltage relay is prevented.
