Electric power inverter

An electrical machine, comprising a body and an electric power inverter one of axially and radially arranged on the body, wherein the electric power inverter includes:

• a capacitor board including a plurality of capacitors, and at least one semiconductor board including a plurality of power semiconductors;
• the capacitor board and the at least one semiconductor board electrically interconnected and mutually stacked in a stacking direction, with a clearance, in a stack formation;
• the plurality of capacitors arranged on the capacitor board in the stacking direction and fitted to a side thereof facing the at least one semiconductor board;
• wherein the plurality of capacitors are arranged on the capacitor board such that at least one open location space is defined between the plurality of capacitors and the capacitor board, the at least one open location space configured to accommodate the at least one semiconductor board;
• and
• wherein the at least one semiconductor board is arranged within the at least one open location space with a clearance to the capacitor board.
