A capacitor support system includes a support structure configured to support at least one capacitor and a pressure generating module configured to generate a pressure on the at least one capacitor. The pressure generating module includes a bearing plate, a transmission plate, and at least one plate shaped leaf spring provided between the bearing plate and the pressure transmission plate. The pressure generating module is connected to the support structure by the bearing plate. The bearing plate is fixedly connected to the connecting structure in such a way that it provides a bearing surface for the at least one leaf spring and keeps the at least one leaf spring in a compressed state between the bearing plate and the at least one capacitor.
