Abstract

Un sistema de carga para cargar una batería incluye un rectificador que transforma la energía recibida de una fuente de alimentación de CA en una señal de CC para cargar la batería y un circuito de detección de arco que mide el ruido agregado a la señal de CC y genera una señal de ruido medida. Un procesador analiza la señal de ruido medida para detectar un arco en serie y, cuando se detecta un arco en serie, provoca una derivación de la corriente CA del rectificador durante un período de tiempo para reducir la salida de CC del rectificador hacia cero. Se inserta un circuito de detección pasiva de arco entre el rectificador y la batería e incluye un condensador de filtro y una resistencia de detección en paralelo con un condensador de filtrado. Se amplifica, digitaliza y emite un voltaje a través de la resistencia de detección como la señal de ruido medida. La señal de CC se puede explorar para obtener la señal de ruido medida en diferentes ventanas de frecuencia.
