Resumen

El uso generalizado de convertidores basados en electrónica de potencia ha resultado en una mejora continua en la confiabilidad de los interruptores de potencia. Los autores anteriores muestran una tasa de fallas de los módulos IGBT de potencia media de 0,1 fallas por 106 h, muchas aplicaciones críticas necesitan una mayor garantía de funcionamiento. Este capítulo ha mostrado una muestra de las técnicas utilizadas para aumentar el rango operativo del sistema en condiciones adversas. Algunas técnicas se aplican antes del inicio de la falla de un dispositivo, al permitir que el dispositivo se salga de la línea para la "recuperación". Otras técnicas modifican la topología, ya sea deshabilitando los dispositivos defectuosos o también incluyendo elementos adicionales para reemplazar los defectuosos. En la mayoría de los casos, esta operación necesita un cambio correspondiente en la estrategia de control, así como en la cantidad de energía que el sistema puede manejar durante esta operación tolerante a fallas.
