A transformer-less DC-DC Modular Multi-level
Converter (DC-DC-MMC) topology based on H-bridge cells is
proposed in this paper. The suggested DC-DC-MMC can be
used to either control the power flow in a HVdc grid or
interconnect HVdc lines with different voltage levels. Branch
energy and current control loops are presented as well as a
cell capacitor voltage balancing strategy. Finally, the operation
of the converter is validated by means of PSCAD simulations.
Results for the operation of the DC-DC-MMC controlling the
power flow between two HVdc grids with different voltage levels
are presented. [-]
