A distributed power system for delivering DC power to a plurality of
loads. A plurality of power converter modules having associated therewith
a DC/DC power conversion operation are provided, each disposed proximate
an associated one of the loads, each of said converter modules having
associated therewith a switching pulse generator for generating switching
pulses. A distributed power line distributes input power to each of the
modules. A data communication line distributes command data between the
modules. Each of the modules includes a power regulation section for
receiving the input power to generate a DC output by controlling the
operation of the switching pulse generator. It also includes a processing
section for interfacing with the data communication line for interfacing
with the commands, the processing function operating in at least a slave
mode to receive commands from the data communication bus. At least one of
the modules operates in both a slave mode and a master mode. In the
master mode, the processing section generates commands for transmission
over the data communication line to an addressed one of the other of the
modules and internally for use in the local slave mode of operation. The
processing section in the slave mode of operation is operable to
configure and monitor the operation of the power regulation section.
