AB  - Interconnection of High Voltage Direct Current (HVDC) links into networks is key to a future HVDC grid spanning large parts of Europe. Different factors including the evolution of cable technology will lead to a variety of DC voltages and a need to provide a DC/DC step up/down at high power ratings (beyond 500 MW). This paper analyses a High Voltage (HV) DC/DC converter utilising an intermediated AC link between two modular multi-level converters (MMC) based on the Alternate Arm Converter (AAC) topology. System operation is demonstrated using a detailed simulation. Power loss estimates derived from the simulation are provided to illustrate the dependence of efficiency on design choices and operating point. Furthermore, the system is shown to block a DC-side fault and prevent its affect from propagating through the system.
