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 27):
A method of controlling a multilevel modular voltage converter, the converter serving to convert an AC voltage into a DC voltage, and vice versa, and including 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 having a plurality of legs, each leg comprising an upper arm and a lower arm, each arm having a plurality of submodules that are individually controllable by a control member of the submodule and comprising a capacitor connected in series in the arm when the control member of the submodule is in an ON state, each arm being suitable for being modeled by 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 method further comprising slow control of the converter in which the voltage across the terminals of each modeled capacitor of each leg is regulated and the voltage across the points of common coupling between the converter and the DC power supply network is regulated by controlling said control members of the submodules of the converter,\n wherein said method comprises calculating a setpoint for the internal energy of the converter stored in the capacitors of the submodules of the arms by using a function having an adjustable input parameter, and calculating a setpoint for the voltage across the terminals of each modeled capacitor from said setpoint for the internal energy of the converter, the setpoint for the voltage across the terminals of each modeled capacitor being 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.
