Patent ID: 8564990

Claim:
A converter apparatus for producing a plurality of output voltages or a plurality of output voltage potentials at corresponding outputs, the converter apparatus comprising: a plurality of setting units, which are each associated with one of a plurality of input voltage sources, each of the setting units being configured to vary a respective input voltage which is produced by the associated input voltage source, and to provide an intermediate voltage, respectively; a plurality of selection elements each being configured to have intermediate voltage potentials applied thereto, the intermediate voltage potentials being defined by the intermediate voltages, each selection element being configured to select one of the intermediate voltage potentials for outputting as the respective output voltage potential, respectively, wherein the voltage outputs of the setting units are connected to one another in series such that the intermediate voltages are added, and the respective intermediate voltage potential is produced at some or each of the voltage outputs, for selection by a respective one of the selection elements; and a control unit configured to control the plurality of setting units such that the setting units produce intermediate voltage potentials which contain the output voltage potentials to be produced, to select in each case one of the intermediate voltage potentials, and to produce the one of the intermediate voltage potentials at a corresponding output, respectively.
