Patent ID: 11044839

Abstract:
An electric power inverter may include a capacitor board having a plurality of capacitors, and at least one semiconductor board 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 may be fitted to a side thereof 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 location space positioned to accommodate a respective one of the at least one semiconductor board. The at least one semiconductor board may be arranged within the respective location space, with a clearance to the capacitor board. The power semiconductors may constitute a power circuit with at least one phase terminal, which, via a respective phase terminal stud, may extend to the capacitor board in the stacking direction and may be brought out to the exterior through the stack formation. The respective phase terminal stud may penetrate the stack formation through a respective phase terminal opening.
