1. An apparatus comprising:
a first power source to generate first voltages;
a power switch to supply the first voltages to a load as load voltages or not supply the first voltages to the load;
first sensors to sense first sensed voltages based on the first voltages, and load sensors to sense the load voltages to produce sensed load voltages; and
a controller to monitor the first sensed voltages and the sensed load voltages and to:
upon detecting a failure of the first sensors, identify a faulty sensed voltage of the first sensed voltages caused by the failure based on at least the first sensed voltages and whether the power switch supplies or does not supply the first voltages to the load;
compute a reconstructed sensed voltage to replace the faulty sensed voltage based on healthy sensed voltages of the first sensed voltages that are not faulty; and
monitor the healthy sensed voltages and the reconstructed sensed voltage.
