Abstract: A system for producing plastic containers with a heating device for heating plastic preforms, wherein the heating device has a transport device for transporting plastic preforms along a predetermined first transport path, and a plurality of holding devices for holding the plastic preforms and at least one heating device which heats the plastic preforms during the transport thereof and comprising a forming device for forming the plastic preforms to form plastic containers. The forming device is configured for expanding the plastic preforms heated by the heating device by applying a flowable medium, and includes a plurality of forming stations which form the plastic preforms to form the plastic containers. Both the heating device and the forming device have changeable elements, wherein the system has a changing device configured for changing both changeable elements of the heating device and changeable elements of the forming device.

Abstract: Bidirectional power conversion systems provide the ability to change power attributes to and from a component. Current bidirectional power conversion systems use a unidirectional power converter for each direction. The integration of the two normally independent power converters results in a bidirectional power converter with nearly half the size, weight, volume, cost and complexity. Described are embodiments of bidirectional power conversion systems that allow power transfer between two or more components without requiring the use of separate unidirectional power converters.
