Abstract:
The invention relates to a modular multilevel converter ( 2 ) having a control module ( 4 ) and a computer ( 10 ) for computing a setpoint for the internal energy of the converter stored in the capacitors of the submodules of the arms. The control module is configured to deduce, from the setpoint for the internal energy of the converter, a setpoint for the voltage across the terminals of each modeled capacitor, which setpoint is used for regulating the voltage across the points of common coupling between the converter and the DC power supply network and the voltage across the terminals of each modeled capacitor.

Claim (Index 17):
A multilevel modular voltage converter for converting an AC voltage into a DC voltage and vice versa, the converter comprising a DC portion for connection to a DC power supply network and an AC portion for connection to an AC power supply network, the converter comprising a plurality of legs, each leg comprising an upper arm and a lower arm, each arm comprising a plurality of submodules that are individually controllable by a control member specific to each submodule, and each submodule comprises a capacitor that is connectable in series in the arm when the control member of the submodule is in an ON state, each arm being suitable for modeling as a modeled voltage source associated with a duty ratio depending on a number of capacitors connected in series in the arm, each modeled voltage source being associated in parallel with a modeled capacitor corresponding to a total capacitance of the arm, the converter further comprising a converter control module configured to regulate the voltage across the terminals of each modeled capacitor of each leg and to regulate the voltage across the points of common coupling between the converter and the DC power supply network by controlling said control members of the submodules of the converter,\n wherein the control module of the converter comprises a computer for computing a setpoint for the internal energy of the converter stored in the capacitors of the submodules of the arms by applying a function having an adjustable input parameter, the control module being configured to deduce from this energy setpoint a setpoint for the voltage across the terminals of each modeled capacitor used for regulating the voltage across the points of common coupling between the converter and the DC power supply network and the voltage across the terminals of each modeled capacitor.
