Abstract
An object of the invention is to improve the cooling performance for a bus bar and a smoothing capacitor in an electric power converter. The electric power converter of the present invention includes a power semiconductor module including a power semiconductor element that converts a DC current to an AC current, a capacitor cell that smooths a DC voltage, a bus bar that electrically connects the power semiconductor module and the capacitor cell, a base plate that is disposed between the bus bar and the capacitor cell, and a sealing material that seals the capacitor cell, the bus bar, and the base plate. The base plate forms an opening through which a capacitor terminal extending from the capacitor cell passes.
