Abstract

A submodule (SMA) for a modular multilevel converter comprises a capacitor (CSM), a first group of series-connected switching units and a first chain link branch comprising a first chain-link (CL1), wherein the first group of switching units is connected in parallel with the capacitor (CSM) and wherein a first switching unit (SUi) comprises a first switching element (T1) with a first anti-parallel unidirectional conducting element (Di) and a second switching unit (SU2) comprises a second switching element (T2) with a second anti-parallel unidirectional conducting element (D2). The first switching element (T1) is controllable to be turned on via a control terminal and to be turned off through reverse-biasing. The first chain link branch is connected in parallel with the first switching unit (SU1). The first chain-link (CL1) comprises cascaded cells controllable to provide voltage contributions combinable to form positive and negative voltages across the first switching element.
