Abstract

"PROCEDIMENTO E DISPOSITIVO DE COMPENSAçãO DE CAMPO MAGNéTICO DE BAIXA FREQuêNCIA NUMA UNIDADE DE ACOPLAMENTO DE SINAL INDUTIVO". Procedimento e dispositivo de compensação de campo magnético de baixa freq³ência numa unidade de acoplamento de sinal indutivo no qual a unidade de acoplamento compreende um núcleo ferromagnético (30) que envolve um condutor pelo qual circula uma corrente (1) de baixa freq³ência para injetar-lhe um sinal de alta freq³ência, caracterizado por detectar a corrente (1) que circula pelo condutor ou campo magnético (3) gerado na unidade de acoplamento, e se obter uma corrente de compensação a partir do valor obtido na detecção realizada e se injetar a corrente de compensação obtida na unidade de acoplamento através de um filtro passa-baixo (9) para gerar um campo magnético (4) igual e de sentido contrário ao produzido pela corrente (1) do condutor em dita unidade de acoplamento e assim evitar a saturação do núcleo magnético (30) sem agregar perdas de inserção. Aplica-se em geral a sistemas de comunicação que requeiram a injeção de sinal de radiofreq³ência sobre um condutor, e em particular, a sistemas que utilizam a rede elétrica como meio de transmissão.
