A distributed power system delivers DC power to a plurality of loads. The
distributed power system includes a plurality of power converter modules
having an associated DC to DC power conversion operation. Each of the
modules includes a power regulation section for receiving a distributed
input power from a distributed power line to generate a DC output by
controlling the operation of the switching pulse generator. A processing
section within the module interfaces with a data communications line for
interfacing with the commands. The processing section is capable of
operating in both a slave mode to receive commands from said data
communication bus and a master mode for generating the commands. In at
least one of the modules operating in the master mode, the processing
section generates the commands for transmission over the data
communications line to an address of one of the other modules. Processing
sections in the slave mode of operation are configurable to monitor the
operation of said power regulation section. Processing sections in the
slave mode of operation are further able to negotiate among active slaves
for assignment of a selected module as a new master responsive to the
failure of a previous master.
