Abstract:
1. A power converter arrangement comprising: at least two static switching element bridges, the static switching element bridges being alternatively operable; a housing that encloses the at least two static switching element bridges, each of the two static switching bridges including a plurality of static switching elements; a plurality of heat sinks, wherein each heat sink is connected to a respective one of the plurality of switching elements; and a cooling system within the housing and shared by the at least two static switching element bridges, the cooling system generating an air flow within the housing for cooling the at least two static switching element bridges, wherein each static switching element bridge has a plurality of branches, each branch including respective static switching elements of the plurality of static switching elements, and each branch is connected to a respective phase of a multi-phase ac input voltage, and wherein corresponding branches of each of the static switching element bridges connected to the respective phase of the multi-phase ac input voltage have a corresponding ac bus bar, and the branches of each static switching element bridge are connected to common dc bus bars.
