Abstract:
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.
