A New MMC Converter With Fault Blocking Capability for HVDC Interconnects
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2017, Vol 5, Issue 1
Abstract
This work proposes a modular multilevel dc/dc converter, named the DC-MMC, that can be conveyed to interconnect HVDC systems of various or comparable voltage levels. Its key elements include: 1) bidirectional power stream; 2) step-up and step-down operation; and 3) bidirectional fault blocking like a dc electrical switch. The part of the DC-MMC is another class of bidirectional singlestage dc/dc converters using interleaved strings of fell sub modules. The DC-MMC operation is broke down and an open circle voltage control procedure that guarantees control adjust of every sub module capacitor by means of coursing air conditioning streams is proposed through fuzzy logic controller. simulation results were investigated in MATLAB programming.
