Abstract
Description
Claims (1)
- DSP로부터 생성되는 디지털 제어부의 제어 출력 신호에 의해 제어 출력을 제어하는 베이스 드라이버로 구성되는 전력제어 스위칭 신호 제어장치에 있어서,상기 DSP로부터 생성되는 제어 출력신호를 보내는 출력신호선과,상기 출력신호선에 일단이 연결되고 타단이 베이스 드라이버로 연결되는 제1포토커플러와,상기 베이스 드라이버 내부에 설치되되 일단은 베이스 드라이버와 연결되고, 타단은 IGBT 모듈과 연결되도록 설치되는 제2포토커플러로 구성되어IGBT 모듈로 출력신호를 보내는 신호는 DSP 컨트롤러로부터 베이스 드라이버까지 신호가 전송되는 사이에 포토커플러를 거치고, 상기 베이스 드라이버로부터 IGBT 모듈까지 신호가 전송되는 사이에 다시 한번 포토커플러를 거치게 됨으로써 노이즈 방지 및 절연을 할 수 있도록 하는 것을 특징으로 하는 전력제어 스위칭 신호 제어장치에서 포토커플러를 사용한 2중 절연 구조.
