Many advantages of distributed power system prompted its use in these
applications. First, with fast dropping on supply voltage of digital system, it is not
realistic to delivery the power with such low voltage. DPS uses much high voltage
to distribute power. This greatly reduces the loss associated with power
distribution. Second, since the second stage (load converter) is placed very close
to the load. The impact of parasitic is minimized. This converter can have very
fast transient response to provide the fast current slew rate to the load. Third, for a
distributed power system, front-end converter is independent of the load
requirement. Each load converter is also independent to other load. This provides
significant benefit for the fast changing system requirement. With distributed
power system, when technology changes, only the load converter associated with
that load need to be redesigned, the impact on whole system is minimized.
