Abstract: A power converter includes an apparatus for enclosing a power unit, which is at least partially inside and/or on a heat sink, and for centering a control unit with respect to the power unit. The power unit includes a semiconductor component and a substrate. The apparatus includes a frame designed to at least partially, preferably completely, surround the substrate, two protruding pieces of a first type designed to engage in a recess or an opening in a heat sink, a protruding piece of a second type designed to engage in a recess or an opening in a control unit, and a fixing element, with at least one of the two protruding pieces of a first type and the fixing element being connected to one another and designed to project in opposite directions. The control unit includes an electronic component and is connected to the power module by the fixing element.
