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