  • Phase module for a power converter
    Patent number: 10985669
    Abstract: A phase module for a power converter includes first and second busbars and at least two semiconductor modules. The first busbar is connected to AC voltage connections of the semiconductor modules. The second busbar is connected to DC voltage connections of the semiconductor modules. At least one section of the first and second busbars is arranged at a distance to one another, the value of which is less than half the value of the distance between the AC voltage connection and the DC voltage connection of one of the semiconductor modules. At least one of the busbars has a separator arranged at a right angle on the remaining part of the busbar and connecting the busbar to at least one of the DC voltage connections or one of the AC voltage connections of one of the semiconductor modules. The separator is arranged along a surface of the one semiconductor module.
