Electric power inverter

An electric power inverter may include a capacitor board having a plurality of capacitors, and at least one semiconductor board each having a plurality of power semiconductors. The capacitor board and the at least one semiconductor board may be mutually stacked in a stacking direction, with a clearance, in a stack formation, and may be electrically interconnected. The capacitors may be arranged in the stacking direction, and fitted to a side facing the at least one semiconductor board. The capacitors may be arranged on the capacitor board to form at least one open location space between the capacitors, each positioned to accommodate one semiconductor board. Each semiconductor board may be arranged within the respective location space with a clearance to the capacitor board. At least some of the capacitors may be arranged in the middle of the capacitor board and each semiconductor board may be arranged on an edge of the capacitor board, so that current paths on the capacitor board may extend generally radially from the middle to the edge of the capacitor board.
