Abstract
Power module for a current converter, particularly a frequency converter, having at least one printed circuit board equipped at least with power components and having a heat-conducting connection with a wall of the current converter housing serving as heat sink, the power module having electrically conducting connection parts arranged vertically to the housing wall, which parts laterally confine a chamber and are long enough to enable accommodation of large, passive electrical components, such as capacitors, in the chamber. To ensure a space saving embodiment of the power module, though maintaining a sufficient heat dissipation and simplifying the electrical connection between the power module and the remaining components of the converter, it is provided that the only electrical connection between the power module and other electrical components of the converter as well as to the supply mains and to a load supplied via the converter is established via the connection parts.
