Abstract
A method of detecting and disabling a failed power supply in a redundant power supply system is disclosed. The method includes detecting, via a first controller, an output voltage and an output current of a first power supply providing power to the redundant power supply system. The first controller determines if the output voltage is greater than a maximum output voltage threshold and in response to determining that the output voltage is greater than the maximum output voltage threshold, the first controller determines if the output current is equal to zero. In response to determining that the output current is not equal to zero and not less than a common share bus current, the first power supply is disabled such that the first power supply does not provide power to the power supply system.
