Capacité Virtuelle
Abstract
The invention relates to a modular multi-level converter (2) provided with a control module (4) and a calculator (10) for calculating a set value for the internal energy of the converter, stored in the capacitances of the sub-modules of the half-arms. The control module is designed to deduce, from said set value for the internal energy of the converter, a set value for the voltage at the terminals of each modelled capacitor used to regulate the voltage at the points of connection of the converter to the continuous power supply network and the voltage at the terminals of each modelled capacitor.
