Patent ID: 8363387

Claim:
A modular converter arrangement comprising: a receptacle for receiving a plurality of converter assemblies forming respective main modules and each including submodules, of a switching module and a capacitor module; wherein said receptacle has at least one connection device for the circuit-conforming electrical connection of said converter assemblies and a rail system for each converter assembly for the mechanical arrangement of said converter assemblies; wherein said capacitor module has a plurality of capacitors, at least one DC voltage contact device for electrical connection to a DC voltage contact device of an assigned switching module and to said connection device of said receptacle, and sliding elements; wherein said switching module has a cooling device, at least one power semiconductor module arranged thereon, an AC voltage contact device and a DC voltage contact device and sliding elements, and wherein the respective sliding elements of the submodules are adapted to be arranged in a stacked manner in the same assigned rails of said rail system of said receptacle so that said connection device of said receptacle forms a first part of a stack, said capacitor module forms a second part of said stack and said switching module forms a third part of said stack and necessary circuit-conforming electrical connections of parts of said stack can thereby be formed.
