마이크로제어기를 사용한 아크 용접기의 제어 시스템 구현

Abstract

본 논문은 아날로그회로의 오차를 제거하면서 부품 수를 줄이기 위하여 싸이리스터 제어형 아크용접기의 제어시스템을 디지털화 하는 방법을 제시하였다. EPLD로 3상 컨버터의 싸이리스터 게이트 발생회로를 구현하였으며, 실험을 통하여 본 논문에서 제시한 방법의 타당성을 확인하였다.

This paper proposes the digitalization method for control system in thyristor controlled arc welding machine in order to delete offsets in analog circuit and reduce the number of devices. The algorithm to generate gating pulses of thyristor at 3-phase controlled rectifier with EPLD is suggested, and the proposed method is verifier with experimental results.
