Abstract
A power supply device for a molding machine with an intermediate circuit, which can be connected with at least one drive of the molding machine and is suitable for supplying the at least one drive with electrical energy; a supply module connected to the intermediate circuit; an energy storage device connected to the intermediate circuit; and a closed loop control device for closed loop controlling an energy content of the energy storage device. The energy storage device can be closed loop controlled by means of the closed loop control device so that the energy content of the energy storage device does not go outside a range, in which a power input and/or a power output of the energy storage device is essentially constant.
