Distributed power supply system having reassignable master |
摘要 |
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.
