  • MMC submodules scale-up methodology for MV and HV power conversion system applications
    Patent number: 11824461
    Abstract: Various examples are provided related to modular multilevel converter (MMC) scale-up control methodologies which can be applied for MV and HV DC applications. In one example, an MMC includes first and second legs each with submodule (SM) groups connected in series, where each SM group includes a plurality of SMs; local group controllers that can control a corresponding SM group; and a central controller that can control output voltage of the MMC via the local group controllers. The local group controllers can provide capacitor voltage balancing (CVB) control of corresponding SM groups.
