Abstract

"SOLDADOR A ARCO ELéTRICO COM ENTRADA DE CA VARIáVEL". A presente invenção refere-se a um soldador a arco elétrico com uma entrada de tensão de CA variável tem um retificador (14) fornecendo CC a um estágio elevador de alta freq³ência ativado (30). O estágio elevador (30) compreende um indutor (62) conectado com primeira e segunda derivações de saída seriais com respectivos enrolamentos primários (42, 44) conectados com respectivos capacitores (C1, C2). Um comutador de alta freq³ência (32) operado por um circuito de controle de fator de potência (34) tem uma condição aberta carregando os capacitores (C1, C2) por corrente através dos enrolamentos primários (42,44) e descarregando o indutor (62) e tem uma condição fechada carregando o indutor (62) e descarregando os capacitores (C1, C2). O estágio elevador (30) tem um estágio de saída de CA compreendendo o enrolamento secundário (52) de um transformador (50) energizado pelo fluxo de corrente nos primeiro e segundo enrolamentos primários (42, 44). Um retificador de saída (100) converte a dita saída de CA em uma primeira tensão de CC que é convertida em uma segunda tensão de CC conectada através do arco de uma estação de soldagem (E,W).
