A power module for a preferably modular medium or high voltage converter or for a power electronic converter of an electric vehicle, comprising - at least one power semiconductor module, preferably an IGBT module, - at least one energy storage module, - at least one cooling device, which cooling device is configured as a cooling plate through which a coolant can preferably flow, - at least one housing part for at least partially covering at least the power semiconductor module, characterized in that the at least one housing part is formed from an electrically conductive material, or has an electrically conductive material at least in a predominant sub-section of its boundary surface, that the power module comprises at least one electrical conductor, formed by a busbar (28, 28'), for transmitting electrical energy between the at least one energy storage module and the at least one power semiconductor module, that the at least one electrical conductor has a first and a second busbar (28, 28'), which are arranged next to or above one another and are electrically insulated from one another, and which first and second busbars (28, 28') are provided for conducting oppositely directed currents, so that their opposing magnetic fields can be at least largely canceled out, and that a short-circuit current attenuation is formed, in which a distance (36, 36') and/or an alignment and/or an area-related overlap between the at least one electrical conductor and the at least one housing part is formed in such a way that the short-circuit current attenuation is not active in the normal operating state of the power module and/or of the modular converter, and that, when a short-circuit-like or short-circuit-induced current increase occurs in the at least one electrical conductor, an inductive coupling can be established between the at least one electrical conductor and the at least one housing part. - at least one power semiconductor module, preferably an IGBT module, - at least one energy storage module, - at least one cooling device, which cooling device is configured as a cooling plate through which a coolant can preferably flow, - at least one housing part for at least partially covering at least the power semiconductor module, the at least one housing part is formed from an electrically conductive material, or has an electrically conductive material at least in a predominant sub-section of its boundary surface, that the power module comprises at least one electrical conductor, formed by a busbar (28, 28'), for transmitting electrical energy between the at least one energy storage module and the at least one power semiconductor module, that the at least one electrical conductor has a first and a second busbar (28, 28'), which are arranged next to or above one another and are electrically insulated from one another, and which first and second busbars (28, 28') are provided for conducting oppositely directed currents, so that their opposing magnetic fields can be at least largely canceled out, and that a short-circuit current attenuation is formed, in which a distance (36, 36') and/or an alignment and/or an area-related overlap between the at least one electrical conductor and the at least one housing part is formed in such a way that the short-circuit current attenuation is not active in the normal operating state of the power module and/or of the modular converter, and that, when a short-circuit-like or short-circuit-induced current increase occurs in the at least one electrical conductor, an inductive coupling can be established between the at least one electrical conductor and the at least one housing part.
