A power management system includes a voltage source configured to provide at least a first voltage and a second voltage, and a controller configured to couple the first voltage to a first voltage supply terminal or couple the second voltage to a second voltage supply terminal in response to a comparison of one or more first variables associated with the first voltage supply terminal to one or more second variables associated with the second voltage supply terminal.

Power management system

A power system provides for redundant input power sources. The power system includes a plurality of inputs that are connectable to a plurality of input sources and an OR circuit coupled to the source inputs. The OR circuit ORs the input sources to provide a source voltage. The power control circuit that is responsive to sufficient source voltage and other commands provides a working voltage to mid- and low-rail converters to provide supply voltages for use by a load.

Redundant input power system

A fault detection system includes a fault indicator and power monitors coupled to the fault indicator. The fault indicator is configured to indicate a fault for a first one of the power monitors which detects a corresponding voltage is not between a corresponding maximum value and a corresponding minimum value.
