Claim:
1. A capacitor module for storing direct voltage, the capacitor module comprising: a capacitor element; a first voltage terminal connected to a first pole of the capacitor element; a second voltage terminal connected to a second pole of the capacitor element; a cooling duct system configured to cool the capacitor element; a housing encapsulating the capacitor element and the cooling duct system, the housing comprising one or more inductor coils inside the housing and configured to smooth current of the capacitor module, each of the inductor coils being connected between a pole of the first voltage terminal and the first pole of the capacitor element so that the first pole of the capacitor element is connected to the pole of the first voltage terminal via the respective inductor coil, wherein walls of the cooling duct system isolate an interior space of the cooling duct system from space surrounding the cooling duct system inside the housing.
