1. A converter unit of modular construction, comprising:
- a mounting frame;
an intermediate circuit capacitor battery secured to the mounting frame and including a plurality of capacitors;
a two-sided cooling unit constructed to support components on both sides of the cooling unit, said cooling unit being secured to the mounting frame above the intermediate circuit capacitor battery and including at least a first mounting plate;
at least one power semiconductor mounted on the first mounting plate and having a control input connected to a terminal of a control assembly;
an intermediate circuit rail system for electrically connecting the plurality of capacitors of the intermediate circuit capacitor battery with each other and with a DC-side terminal of the at least one power semiconductor;
at least one current rail electrically connected with a corresponding AC-side terminal of the at least one power semiconductor; and
at least one cover plate covering the mounting frame so as to form an air channel.

Abstract
A modular converter unit and a power converter assembly having at least one modular converter unit are described. The converter unit includes a two-sided cooling device and an intermediate circuit capacitor battery with several capacitors that are arranged one on top of the other in a mounting frame. A power module with a control component and a conductor rail system is arranged on one or more mounting plates. The mounting frame is finished with metal sheets for forming channel. A compact converter unit can thus be produce a series of universal modular converter assemblies at low cost.
