Abstract
Un sistema de detección de fallas para un sistema que tiene una sola entrada de CD y una pluralidad de cargas de C/A tal como un vehículo eléctrico o eléctrico híbrido. Una pluralidad de inversores convierte CD en C/A trifásica y suministra energía C/A a una carga de C/A individual correspondiente. Cada inversor incluye un transformador de corriente de modo común y un controlador. Un transformador de corriente de modo común individual correspondiente está acoplado a la salida de C/A trifásica del inversor. Un controlador individual correspondiente está acoplado a la salida de un transformador de corriente de modo común individual correspondiente y está acoplado a una carga de C/A individual correspondiente. Cada controlador está configurado para detectar una falla en la carga de C/A individual correspondiente y en el caso de detección de una falla en una carga de C/A individual correspondiente, el controlador correspondiente inhabilita la carga de C/A.
