Patent ID: 8488319

Claim:
A modularly constructed power converter arrangement comprising: a first and a second end-side element; at least one power converter module arranged between said first and second end-side elements; a fan of an air cooling device disposed on said first end-side element; said second end-side element having a plurality of cutouts therein acting as air passages in alignment with said fan; and a heat sink through which flow can take place from said first to said second end-side element and on which is arranged at least one power semiconductor module connected to a control device and to a capacitor device; wherein said capacitor device consists of two capacitor banks arranged in a mirror-inverted fashion with respect to one another; wherein one capacitor bank is arranged, from an end-side consideration, laterally alongside said heat sink and said further capacitor bank is arranged alongside said power semiconductor module; wherein at least one of said first and second end-side elements has an electrical connection device; and wherein said at least one power converter module has a housing, which is open at said end sides and which is adapted to be connected at said end sides to at least one of an end-side element and a further power converter module.
