  • Power phase module of a converter, converter, and vehicle
    Patent number: 11452227
    Abstract: A power phase module has at least one first DC terminal pair on a face of the power phase module with respective connection elements for connection to a current bar pair. The power phase module further has a first DC capacitor terminal pair on the face being spaced apart from the first DC terminal pair and connected in parallel with it and having respective connection elements for connection to an intermediate circuit capacitor module associated with the power phase module. The power phase module further has a first AC terminal on another side of the power phase module and a switching device connected with the first AC terminal and the first DC terminal pair for converting a direct voltage. The power phase module further has a cooling device to carry heat out of the power phase module. Further proposed are a converter and a rail vehicle with a converter.
