ABSTRACT:
A multi-node network having two sets of SCRS, each set comprising a pair of parallel-connected, oppositely-polarized SCRs, the sets being electrically joined to form a common connection whereby electric current can flow through one pair to the common connection, thence to a load and/or to and through the other pair, or electric current can flow through said other pair to the load. Each SCR of the SCR pairs is triggered by transient signals such that the common connection can receive continuous power through either set of SCRs of the power and the connection can be switched between sources.
