摘要：
This paper introduces an MMC based DC-DC converter that can be used to interconnect DC networks of different or similar voltage levels and manage a bidirectional power flow. It provides a DC fault blocking capability at both DC sides and is easily scalable to higher voltage and power ratings due to its modular design. The functional principle of the converter is analyzed and detailed design criteria are provided. The performed analysis is validated by full-scale simulations.
