In this article, asymmetrical modular multilevel converter (A-MMC) topology using mixed cell (SM) with DC-side fault blocking capability and the reduced component count is proposed. The mixed cell submodule is made up of a full-bridge (FB-SM) and a half-bridge (HB-SM) with asymmetric capacitor voltage based on geometric propagation (GP) ratio. Each mixed cell submodule can […]
This research paper introduces a modified single DC-sourced multilevel inverter (MLI) consisting of several cells made from a controlled switch, a diode, and a capacitor to generate voltage levels in series connection with the H-bridge. By increasing the number of cells more output voltage levels can be generated in proposition to 2n+3 for symmetrical multilevel […]
