Patent ID: 8624431

Claim:
A power transmission and distribution system comprising: a power source side; a load side; and a plurality of power converters on each of the power source side and the load side, wherein the power source side converters and the load side converters are each configured to provide a modular stacked dc converter architecture, wherein the connections, on the power source side converters, between the outputs of a first stacked DC-DC power source side converter and a second stacked DC-DC power source side converter are in series to the inputs of a first stacked DC-DC power load side converter and a second stacked DC-DC power load side converter, and further wherein the power source side converters are configured and programmed to share a load equally or in proportion to their individual power ratings, wherein the load sharing associated with each power source side converter is based on a corresponding link current versus average output voltage droop curve programmed therein, and to adjust a corresponding link current versus average output voltage droop curve operating point in response to a corresponding magnitude of link current and a corresponding average output voltage associated with the power source side converter.
