Abstract
Description
Claims (3)
- 입력스위치(SW)등에 의해 단속되는 입력전원(BT1)으로 동작되며 상기 입력전원을 저전압 저전류 전원으로 출력시키는 포토커플러(PC), 상기 포토커플러에서 출력된 저전류 전원을 대전류로 증폭하여 출력하는 전류증폭기(OP), 그리고 상기 전류증폭기에서 출력된 전원을 구동제어 전원으로 인가받아 동작되며 전기적 부하(LD)로 공급되는 차량전원(BT2)을 스위칭하는 스위칭소자(FT)로 구성된 것을 특징으로 하는 단일전원 회로용 전자식 대전류 스위치.
- 제1항에 있어서, 상기 스위칭 소자(FT)가 전계효과 트랜지스터인 것을 특징으로 하는 단일전원 회로용 전자식 대전류 스위치.
- 제1항에 있어서, 상기 스위칭 소자(FT)가 PNP 트랜지스터인 것을 특징으로 하는 단일전원 회로용 전자식 대전류 스위치.
