Abstract
Overvoltage and component failure protection for redundant current-mode controlled power supplies operating in parallel takes a supply off line when the supply drives the output bus to an overvoltage condition, without removing properly functioning supplies from the bus. The supply is also taken off line when either the error amplifier or the PWM fails.
