Abstract
A modular multi-level power converter device including an AC output, including a modular multi-level DC/AC converter including a plurality of arms in parallel, ends of which define input terminals, each arm including two lines of modules in series, each switching module including a pair of switches in series, mounted on terminals of an energy-storage device, the DC/AC converter adjusting frequency at an output of the converter device. The device further includes a converter including a DC output, including two output terminals connected to the input terminals of the DC/AC converter, the converter including a DC output adjusting amplitude at an output of the converter device, the DC/AC converter further including a mechanism controlling the switches of the modules, which apply a full-wave command to the switches during at least one time interval, the modules of a single line being in a same state simultaneously.
