Stromrichtereinheit in Modulbauweise

摘要

The invention relates to a modular converter unit (2) and a power converter apparatus (110) having at least one modular converter unit (2). According to the invention, the converter unit (2) has a cooling device that can be fitted on both sides (8) and an intermediate circuit capacitor battery (10) consisting of several capacitors (38), which are arranged one on top of the other in a mounting frame (6), wherein at least one power module (18) having a corresponding control component (32) and a corresponding conductor rail system (52) is arranged on at least one mounting plate (16) and the mounting frame (6) is completed with metal sheets in order to form a cooling channel. This makes it possible to obtain a compact power block (2) by means of which a series of universal, cost-minimized modular apparatuses can be produced.
