  • Patent number: 8564990
    Abstract: A converter apparatus and method for operating the converter apparatus are provided for producing a plurality of output voltages or a plurality of output voltage potentials at corresponding outputs. The converter apparatus includes a plurality of setting units, which are each associated with one of a plurality of input voltage sources, Each of the setting units is configured to vary an input voltage which is produced by the associated input voltage source, and to provide an intermediate voltage. The converter apparatus also includes a plurality of selection elements to which intermediate voltage potentials are each applied. The intermediate voltage potentials are defined by the intermediate voltages. Each selection element is configured to select one of the intermediate voltage potentials for outputting as the respective output voltage potential.
