  • Initialization system of cascaded modular energy converters
    Patent number: 11979092
    Abstract: A system for limiting charging current of capacitive filters of power cells of a cascaded modular power converter during the start-up period where a low-voltage power source is used, supplying a controlled power switching arrangement controlled by the general controller of the cascaded modular power converter, making it possible to limit the charging current of the capacitors of the power cells during the start-up period of the cascaded modular converter. The controlled power switching arrangement communicates with the general controller of the cascaded modular power converter over a communication channel. The communication means send the commands to start or end the start-up process of the cascaded modular converter.
