Abstract
circuito de tiristor e método de proteção do tiristor. um circuito de tiristor (100) compreende pelo menos uma ramificação compreendendo pelo menos um tiristor (10, 20), um circuito de controle de tiristor (50) e um detector de corrente (60, 61). o detector de corrente (60, 61) é configurado para detectar um valor de corrente representativo de uma corrente elétrica fluindo através do tiristor e para inserir o valor de corrente detectado no circuito de controle do tiristor. o circuito de controle do tiristor é configurado para determinar uma condição de falha na qual o valor de corrente detectado excede um limite de corrente predeterminado com base em uma capacidade de bloqueio deteriorada do tiristor. dependendo do resultado da determinação, o circuito de controle do tiristor aciona o tiristor em um estado condutor.
