Zusammenfassung:	Provided is a modular multilevel converter and a method for synchronizing outputs of sub-modules of the converter. The modular multilevel converter includes sub-modules connected in parallel, and each sub-module generates an output. The modular multilevel converter also includes a controller that is communicatively coupled to the sub-modules. The controller controls a flow of one or more synchronizing signals between the plurality of sub-modules, such that each sub-module receives the synchronizing signals in opposite directions simultaneously, thereby controlling a synchronization of the outputs generated by the sub-modules. 200a 200b 200n Analog/Digital 220S System Control 240 Sub-module communications bus
