Abstract

See full text

A system and method for proportioned power distribution in arrays of power converters are disclosed. According to one embodiment, a method includes distributing a node-specific transfer function to each node of a plurality of nodes via a communication bus. Each node includes a power converter, and nodes of the plurality of nodes are electrically connected in series. Each node-specific transfer function enables each node to contribute a positive impedance to a total impedance of the plurality of nodes. The computer-implemented method further includes coordinating a setting of a parameter of each node-specific transfer function to regulate a common bus current across the plurality of nodes, and assigning to each node an electrical characteristic based on a parameter of each node-specific transfer function.
