Abstract

DISPOSITIVO DE FORNECIMENTO DE ENERGIA A UM FORNO A ARCO. A presente invenção refere-se a um dispositivo de fornecimento de energia para fomos a arco com um retificador (1), retificador (1) esse que em seu lado de tensão alternada pode ser conectado a uma rede elétrica de fornecimento de tensão alternada (2) e no seu lado de tensão contínua é conectado com um circuito de tensão contínua (3). Além disso, o dispositivo de fornecimento de energia para fomos a arco compreende um inversor (4), o qual em seu lado de tensão contínua é conectado a um circuito de tensão contínua (3) e no seu lado de tensão alternada com pelo menos um eletrodo a arco (5). Para melhoria da estabilidade e queima por igual do arco, o inversor (4) é projetado como um inversor que aplica uma tensão alternada retangular ao arco de eletrodo (5).
