Abstract: An arrangement for a modular inverter includes a number of power semiconductors and cooling elements, where the cooling elements are connected to the power semiconductors for cooling the power semiconductors. The power semiconductors and the cooling elements are disposed around a center axis of the arrangement in such a manner that they demark a channel around the center axis in which a cooling medium is able to flow in the direction of the center axis. The arrangement includes a first tube-shaped ring film capacitor around the center axis of the arrangement. The power semiconductors are arranged between the cooling elements and an inner surface of the first tube-shaped ring film capacitor.

Abstract: A capacitor fastening for fastening a capacitor to a panel, whereby the capacitor, when mounted in place, is positioned in the panel, fastened at its lower part. The capacitor fastening includes a retainer in the panel at the mounting point of the capacitor for preventing lateral movement of the capacitor in at least one selected direction; a tightening plate arranged above the panel and to be fastened to the panel, which tightening plate has a hole substantially corresponding to the diameter of the capacitor above the mounting point of the panel; and a wedge between the panel and the tightening plate for tightening the retainer of the panel and the edge of the hole in the tightening plate from opposite directions against the capacitor.
