Bus holdup circuit for a distributed power system and method of operation thereof
First Claim
1. For use with a module of a distributed power system having a backplane interface adapted to be removably coupled to a DC backplane of said distributed power system, a bus holdup circuit, comprising:
- an energy storage circuit, coupled across said backplane interface, adapted to store and dissipate energy to bolster a voltage across said DC backplane; and
an inrush limiting circuit, series-coupled to said energy storage circuit, adapted to limit an inrush current to said module.

Abstract
A bus holdup circuit for a module of a distributed power system, a method of bolstering bus voltage and a distributed power system employing the circuit or the method. In one embodiment, wherein the module has a backplane interface adapted to be removably coupled to a DC backplane of the distributed power system, the bus holdup circuit includes: (1) an energy storage circuit, coupled across the backplane interface, adapted to store and dissipate energy to bolster a voltage across the DC backplane and (2) an inrush limiting circuit, series-coupled to the energy storage circuit, adapted to limit an inrush current to the module.
