Abstract
A redundant power supply system wherein the standby power supplies are maintained in a powered up state at all times by feeding back a difference signal which is indicative of the voltage difference between the output of the power supply and a further difference voltage. The further difference voltage is indicative of the voltage drop across a diode located between the output from the power supply and the load of the entire power supply system.
