- it has to be easy to install, easy to replace the submodules and, secondly, to have them Care must be taken to ensure that adjacent components are not damaged in the event of a short circuit due to the escape of hot gases or plasma.
- This is essential in particular when using molded power semiconductors, since the bonding wires usually melt due to the high short-circuit currents, as a result of which an arc is formed in an explosive manner.
- an easily mountable cost-effective multilevel power converter is provided, since a cost-intensive complex additional support structure for the submodules has become superfluous.
- a plurality of power converter modules are fastened to a respective energy storage carrier.
