Abstract

La presente descripción proporciona sistemas y métodos para proteger un suministro de energía en modo de conmutador (SMPS). Un SMPS puede incluir un conector de energía de entrada, un rectificador y filtro de entrada, un transformador, un rectificador y filtro de salida y un conector de energía de salida. Un circuito de control puede generar selectivamente una señal de conmutación para impulsar el transformador en base en una señal de retroalimentación y una señal de protección generada por un circuito de protección. El circuito de protección puede generar la señal de protección con un ciclo de trabajo asimétrico que oscile entre un estado habilitado y un estado inhibido. La señal de protección puede inhibir al circuito de control evitando que genera la señal de conmutación cuando la señal de protección está en un estado inhibido. Un circuito de detección puede recibir la señal de retroalimentación y forzar selectivamente la señal de protección a un estado habilitado cuando la señal de retroalimentación indica que un voltaje de salida es demasiado alto.
