본 발명은 저전압릴레이를 갖는 스마트 PRA와 이를 이용한 스마트 PRA의 페일세이프티 시스템 및 방법에 관한 것으로, 더욱 상세하게는, 고전압릴레이를 대체하여 저전압릴레이인 래치릴레이와 IGBT로 구성한 저전압릴레이를 갖는 스마트 PRA와, 충격과 진동 등에 의해 래치릴레이의 접점이 떨어졌을 경우 IGBT로 과전류가 흘러 소손되는 것을 방지하기 위한 스마트 PRA의 페일세이프티 시스템 및 방법에 관한 것이다.
The present invention relates to a smart power relay assembly (PRA) with a low voltage relay, a fail safety system using the smart PRA with the low voltage relay, and a fail safety method using the fail safety system. More specifically, the present invention relates to a smart PRA with a low voltage relay formed with a latch relay that is a low voltage relay in place of a high voltage relay and an IGBT, a fail safety system and a method using the smart PRA to prevent an overcurrent from flowing to the IGBT to be damaged by a fire when a contact point of the latch relay falls due to shocks or vibration.
