POWER CONVERTER WITH DUAL RING NETWORK CONTROL

摘要

A method for providing electric power to a power system includes receiving, at a slave node of a power converter having a plurality of slave nodes, a first synchronization signal via a first communication channel, the first synchronization signal purporting to represent a master timing characteristic of a master control node of the converter; receiving, at the slave node of the converter, a second synchronization signal via a second communication channel, the second synchronization signal purporting to represent a master timing characteristic of the master control node of the converter; synchronizing an internal timing characteristic of the slave control node with the master timing characteristic of the master control node using the first synchronization signal; determining that the first synchronization signal is invalid; and synchronizing an internal timing characteristic of the slave control node with the master timing characteristic of the master control node using the second synchronization signal.
