Abstract
Embodiments of a modular direct current interconnection device (MDCID) include at least three operation branches, at least one transient branch, and a local controller. Each of the operation branches includes a first terminal coupled to a common node and configured to transmit DC current in a normal mode. The transient branch is coupled between second terminals of different ones of the at least three operation branches and configured to provide a transient DC current path in a fault clearance mode. The local controller is coupled to the operation branches and the transient branch, and the local controller is configured to control operation of the operation branches and the transient branch.
