Abstract

In this paper, an asymmetric mixed MMC topology of multilevel converter for bipolar HVDC transmission systems is introduced. Among the existing MMC topologies for the bipolar HVDC systems, the asymmetric mixed MMC topology provides the benefits of: A lower number of submodule cells, fewer switching devices and lower conduction losses. Furthermore, the HVDC based on asymmetric mixed MMC can be flexibly operated at a reduced DC voltage, even zero DC voltage under DC line fault conditions. Also, the flexible DC voltage controllability in asymmetric mixed MMC permits a slow rampup along the DC line fault recovery characteristics. Finally, the full-scaled simulation results and the experimental results with a scaled version in laboratory are provided to support the validity of the asymmetric mixed MMC for bipolar HVDC system.
