Abstract

Un filtro condensador-inductor (LC) diseñado para cumplir con normas EMC (Compatibilidad Electromagnética) comprende condensadores; interruptores para acoplar condensadores; inductores de modo diferencial para acoplar condensadores e interruptores; e inductores de modo común o una combinación de inductores de modo diferencial e inductores de modo común, donde una señal de entrada cambia la inductancia de los inductores de modo diferencial en el filtro LC para modificar una respuesta de frecuencia del filtro LC. En el filtro LC, los inductores de modo diferencial comprenden además inductores de bobinado múltiple idénticos, y la señal de entrada, la cual desvía la pluralidad de inductores de modo diferencial, incluye una señal DC o una combinación de señales DC y AC. Una frecuencia de esquina del filtro LC se ajusta y aproxima como fc= 1/(2 x pi x sprt (LxC) ), donde fc es la frecuencia de esquina, L es un valor compuesto de inductancia, y C es un valor compuesto de capacitancia.
