Abstract

The invention relates to a modular converter cabinet system of a converter comprising at least one phase module (1, 3, 5) having an upper and a lower converter valve (T1,..., T6), wherein each converter valve (T1,..., T6) has at least two converter cells (2) and a branch inductor (LT1,..., LT6), which are electrically connected in series. According to the invention, the modular converter cabinet system comprises a first valve cabinet (24), a second valve cabinet (26) and an inductor cabinet (48), wherein the valve cabinets (24, 26) each have a plurality of valve levels (V1,..., V6) spaced apart one above another and having a plurality of honeycomb cells (46) arranged alongside one another, wherein the inductor cabinet (48) has a plurality of phase levels (P1, P2, P3) spaced apart one above another, and wherein in each case two valve levels (V1, V2; V3, V4; V5, V6) of at least one valve cabinet (24, 26) are electrically conductively connected in each case to the phase levels (P1, P2, P3) of the inductor cabinet (48), which are arranged alongside one another. A converter cabinet system which can be individually adapted to different converter output voltages in a simple manner is thus obtained.
