Abstract
A power supply system includes at least one power supply module and at least one redundant power supply module. A power supply module may include a charging resistor in parallel with an OR-ing device to keep all filter capacitors charged as long as at least one power supply module remains operational. This may avoid current spikes at turn on and may enable the redundant module to turn on without using soft start.
