A distributed power system for delivering DC power to a plurality of loads. A plurality of switching DC/DC converter modules are provided, each disposed proximate one of the loads, and each having associated therewith a switching pulse generator for generating switching pulses. A distributed power line distributes input power to each of the modules and a data communication line distributes command data between the modules, each of the modules uniquely addressable over the data communication line. A timing communication line is also provided for distributing timing information to each of the switching pulse generators. A master controller generates commands and communicates them to the data modules over the data communication line, the master controller operable to generate timing information over the timing communication line to each of the modules for controlling the associated switching pulse generator.
