A control system for controlling conversion of an input power into an output power in at least one converter module (27) comprising at least one input power terminal, at least one output power terminal, and for each output power terminal at least one active switching device (35) connected between the an input power terminal and the respective output power terminal, by controlling the timing of the switching of the at least one active switching device (35) is provided. The control system comprises a master controller (33) and, for each converter module controlled by the master controller (33), a communication link (40) interconnecting the master controller (33) and the respective converter module (27). In addition, it comprises a timing generator (45) generating a timing signal having a cycle time equal to or less than the shortest time constant of the converter modules (27) and the immediate power circuit elements relating to the used respective converter module. The timing generator (45) is integrated in or interconnected with the master controller (33). Furthermore, the control system comprises a signal generator (46) being integrated in or interconnected with the master controller (33) which generates switching control signals, each switching control signal containing a control message defining a switching state for the at least one active switching device (35) in a converter module (27) interconnected with the master controller (33), the duration of each control message being equal to or less than the cycle time. The communication links (40) are serial communication links.
