Summary: | The invention relates to an electric power inverter (10) for an electrical machine of an electrically powered drive system. The electric power inverter (10) incorporates a capacitor board (20) havinga plurality of capacitors (21), and a at least one semiconductor board (30) having a plurality of power semiconductors (31), which are mutually stacked in a stacking direction (11), with a clearance,in a stack formation (12), and are electrically interconnected. According to the invention, the plurality of capacitors (21) are arranged on the capacitor board (20) in the stacking direction (11), and are fitted to a side thereof facing the at least one semiconductor board (30). The plurality of capacitors (21) are arranged on the capacitor board (20) to form at least one open location space (23)between the capacitors (21) and the capacitor board (20), each location space (23) positioned to accommodate a respective one of the at least one semiconductor board (30), and the at least one semiconductor board (30) is arran |
