Abstract
Description
Claims (1)
- 입력측 인버터부의 고주파 교류출력을 강압, 정류하여 리액터와 콘덴서에 의하여 평활하게한 직류를 출력측 인버터부에서 극성반전시켜 다시 교류로 변화하여 아크부하에 공급하고, 입력측 인버터부에서 출력전류를 제어하는 아크 용접용 전원에 있어서, 소정의 위상차를 가진 2개의 제어용 구형파신호를 발생하는 수단과, 정상의 출력전류치를 설정하는 제1의 전류설정기와, 극성반전시의 출력전류치를 설정하는 제2의 전류설정기와, 상기 구형파신호중 진행위상의 구형파신호의 상승, 하강에 동기하여 전류제어계의 출력전류설정치를 상기 제1의 전류설정기의 설정치로 부터 상기 제2의 전류설정기의 설정치로 이행시키는 전류 제어회로와, 상기 양 구형파신호중 지연위상의 구형파신호의 상승, 하강에 동기하여 출력측 인버터부를 반전 동작시키는 구동회로를 구비하고, 출력전류치가 상기 제2의 전류설정기의 설정치와 대략 같아졌을 때에 출력전류의 극성반전을 행하도록 한 것을 특징으로 하는 아크 용접용 전원의 제어장치.
