Abstract

As this paper is related to the relay and its driving control method, it explains about the relay which connects or interrupts the DC high voltage battery's power to drive the electric car's inverter. The paper suggests a sub-relay which prevents strong sparks from relay's contact point when the relay connects to the DC high voltage battery and also compensates for the increasing internal resistance value that is caused by deterioration at contact point. The relay's rated power is approximately 10KW and the relay's electric property has been verified through electrical instantaneous power short test, etc.

본 논문은 릴레이 장치 및 구동 제어 방법에 관한 것으로서, DC 고전압 배터리의 전력을 전기자동차의 인버터를 구동하기 위해 전력을 접속하거나 차단하는 릴레이에 관한 것이다. 본 논문을 통해 DC 고전압 배터리에서 릴레이가 접속되는 순간 릴레이의 접점에서 강한 스파크가 발생하는 것을 방지하고 접점의 열화 및 노후로 인해 증가하는 릴레이 내부 저항값을 보상하기 위한 서브릴레이가 제안되었다. 제작된 릴레이의 정격 전력은 10KW 정도이며 전기적 순단시험 등을 통해 릴레이의 전기적 특성을 검증하였다.
