Abstract
Un sensor de corriente (10) para detectar corriente alterna (AC) a través de una impedancia de carga (14) de un circuito eléctrico. Los componentes del sensor se fabrican adentro de un tablero de multiples capas (Figura 3). El sensor incluye un circuito transformador que incluye una bobina primaria (32) acoplada en serie con la línea de corriente (16, 18) del circuito eléctrico. La bobina primaria (32) incluye elementos de línea de corriente (20A, 20B) en forma de franjas conductoras. El transformador secundario (30) comprende primera y segunda bobinas eléctricamente conductoras (30a, 30b) inductivamente a la línea de corriente. Las bobinas secundarias se conectan eléctricamente en serie una con la otra, de tal manera que los voltajes generados a través de las bobinas en respuesta a la corriente de la línea de corriente son aditivos, mientras que se cancelan los voltajes de interferencia que son inducidos en las bobinas por la presencia de campos magnéticos externos o de diafonía entre los sensores adyacentes en el mismo tablero.
