Abstract

a presente invenção refere-se à um circuito de proteção de sobretensão (40?, 41, 42) para um suprimento de energia (100), compreendendo um conversor de energia (20), um circuito de proteção à sobretensão (40?), compreendendo um comparador (oa2). o circuito de proteção à sobretensão (40?, 41, 42) é configurado para usar o comparador (oa2) para comparar a voltagem de suprimento de energia (vdc) com a voltagem de referência, e para produzir um sinal de suprimento de energia de paralização (s41s), no terminal de saída de interrupção da atividade (41s), quando a voltagem de suprimento de energia (vdc) excede a voltagem máxima de suprimento de energia, e para travar o sinal de paralização (s41s) do dito suprimento de energia, no terminal de saída da interrupção da atividade (41s), mesmo se a dita voltagem de suprimento de energia (vdc) subsequentemente cai para um nível abaixo da voltagem máxima de suprimento de energia. o circuito de proteção da sobretensão (40?) ainda compreende um circuito de restabelecimento (41rc), acoplado à primeira entrada (+) do comparador (oa2), o circuito de restabelecimento (41rc) sendo configurado para puxar o nível do sinal na primeira entrada (+), abaixo do dito valor de referência, de tal maneira que o sinal de paralização (s41s) do suprimento de energia é restabelecido, quando um sinal de restabelecimento (s41r) é dado para o circuito de restabelecimento (41rc).
