Abstract

1 / 1 resumo “sensor de corrente, e, mã‰todo para sensorear corrente” um sensor compreende membros de ferrita primã¡rios (362) espaã§ados do sensor de campo magnã©tico (20) em lados opostos do sensor de campo magnã©tico para concentrar ou direcionar uma orientaã§ã£o do campo magnã©tico do sinal observado em direã§ã£o a uma ã¡rea alvo (409) do sensor de campo magnã©tico (20). um sensor de campo magnã©tico (20) sensoreia um componente de sinal de corrente contã­nua ou componente de baixa frequãªncia do sinal observado. um primeiro circuito de filtraã§ã£o tem uma resposta de filtro passa-alta. o primeiro circuito de filtraã§ã£o ã© acoplado com o indutor para fornecer um componente de sinal de corrente alternada filtrado. um segundo circuito de filtraã§ã£o tem uma resposta de filtro passa-baixa. o segundo circuito de filtraã§ã£o acoplado com o sensor de campo magnã©tico para fornecer componente de sinal de corrente contã­nua filtrado. um circuito de fusã£o de sensor determina uma corrente sensoreada agregada com base no componente de sinal de corrente alternada filtrado e no componente de sinal de corrente contã­nua filtrado.
