FIELD: electricity.
SUBSTANCE: multilevel converter (5) comprises at least two serially connected submodules (SM), wherein each submodule (SM) has at least two switches, respectively (10, 20, 30, 40, 210, 220, 410, 420), and a capacitor (C), as well as two current-carrying external terminals (A1, A2) of the module. According to the invention, it is provided that at least one submodule has at least one external heat sink (60, 80, 300, 400) which serves as a current-carrying external terminal (A1, A2) of the module.
EFFECT: reduction of vibrations in a multilevel converter.
