Abstract
Procedimiento y dispositivo de compensación de campo magnético de baja frecuencia en una unidad de acoplamiento de señal inductiva. En el que la unidad de acoplamiento comprende un núcleo ferromagnético (30) que envuelve un conductor por el que circula una corriente (1) de baja frecuencia para inyectarle una señal de alta frecuencia, se caracteriza porque se detecta la corriente (1) que circula por el conductor o el campo magnético (3) generado en la unidad de acoplamiento, y obtiene una corriente de compensación a partir del valor obtenido en la detección realizada, e inyecta la corriente de compensación obtenida en la unidad de acoplamiento a través de un filtro paso bajo (9) para generar un campo magnético (4) igual y de sentido contrario al producido por la corriente (1) del conductor en dicha unidad de acoplamiento y así evitar la saturación del núcleo magnético (30) sin añadir pérdidas de inserción. En general se aplica a sistemas de comunicación que requieran la inyección de señal deradiofrecuencia sobre un conductor, y en particular en sistemas que utilizan la red eléctrica como medio de transmisión.
