Abstract
A method of monitoring condition of a modular multilevel converter, wherein the modular multilevel converter includes submodules having a capacitor and controllable switches. The method including selecting a submodule, controlling the controllable switches of the selected submodule to form a current path through the submodule by controlling at least one controllable switch to a conducting state and at least one controllable switch to a blocking state, disconnecting the voltage of the capacitor of the selected submodule from the submodule, performing measurements on at least one controllable switch that was controlled to a blocking state.
