Abstract
A system for detecting a fault in a power supply having at least one power supply unit and a redundant power supply unit. The system includes a printed circuit board and a common voltage bus disposed on the printed circuit board. A plurality of diodes is disposed on the printed circuit board having first electrodes connected to the common voltage supply bus. The diodes have second electrodes connected to a corresponding one of the at least one power supply unit and the redundant power supply unit. The diodes are connected to the common bus in a logic OR configuration. A controller, disposed on the printed circuit board, is fed by a voltage at the second electrode of a corresponding one of the diodes and a reference voltage for determining whether the voltage at the second electrode of the corresponding one of the diodes is producing a predetermined voltage relative to the reference voltage.
