Design of a Modular Multilevel Converter with 400 kWh of Integrated Batteries

In this paper the electromechanical design and the cascaded signal processing platform of a modular multilevel converter with integrated, second-life battery modules are presented. With its 120 full-bridge submodules, the prototype is designed for a maximum in- and output power of 100 kW and to stor...

Summary:In this paper the electromechanical design and the cascaded signal processing platform of a modular multilevel converter with integrated, second-life battery modules are presented. With its 120 full-bridge submodules, the prototype is designed for a maximum in- and output power of 100 kW and to store up to 400 kWh.
