    • openAccess   A multilevel modular dc-dc converter topology 

      Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Andrade, Iván; Riedemann, Javier; Pesce, Cristián; Belenguer Balaguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Elsevier (2017)
      A multilevel modular DC-DC power conversion topology based on cascaded H-Bridge converters in a double П configuration is presented. The topology is intended to interconnect large power DC networks. A two level control ...

    • openAccess   Modular multi-level DC-DC converter for high-power and high-voltage applications 

      Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Belenguer Balaguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon IEEE (2015)
      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 ...

    • openAccess   Power flow control using a DC-DC MMC for HVdc grid connected wind power plants 

      Vidal-Albalate, Ricardo; Belenguer Balaguer, Enrique; Pesce, Cristián; Soto Sánchez, Diego; Peña, Rubén; Blasco-Gimenez, Ramon; Riedemann, Javier IEEE (2015)
      This paper proposes the use of a transformer-less DC-DC Modular Multilevel Converter (MMC) topology, based on cascaded H-bridge converters, for power flow control in High Voltage Direct Current (HVDC) grids used to ...

    • openAccess   Sizing and Short-Circuit Capability of a Transformerless HVDC DC-DC Converter 

      Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Belenguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (2020-01-15)
      This work aims at optimizing the converter design of the double-T MMC DC-DC converter in terms of transmitted power per submodule and also in terms of transmitted power per silicon area, while, at the same time, providing ...
