Module for a multilevel converter

A module configured as a component of a multilevel converter and having multiple base units and electrical energy sources, wherein:

• each base unit has at least one half-bridge;
• the at least one half-bridge comprises at least one highside switch and at least one lowside switch;
• for two base units, arranged directly adjacent to one another inside the module, a first base unit of the two base units has the at least one highside switch connected to a positive pole of a first energy source and the at least one lowside switch connected to a negative pole of a second energy source;
• and
• a second base unit of the two base units has the at least one highside switch connected to a positive pole of the second energy source and the at least one lowside switch connected to a negative pole of the first energy source, current being able to be transported between two poles via at least one current path.

A multilevel converter having multiple modules, the multilevel converter comprising:

• each module has multiple base units and electrical energy sources;
• each base unit has at least one half-bridge;
• the at least one half-bridge comprises at least one highside switch and at least one lowside switch;
• for two base units arranged directly adjacent to one another inside the module, a first base unit of the two base units has the at least one highside switch connected to a positive pole of a first energy source and the at least one lowside switch connected to a negative pole of a second energy source;
• and
• a second base unit of the two base units has the at least one highside switch connected to a positive pole of the second energy source and the at least one lowside switch connected to a negative pole of the first energy source, current being able to be transported between two poles via at least one current path.
