Apparatus for Voltage Conversion and Onboard Electrical System Having Said Apparatus

摘要

A device for voltage conversion includes a first, transformerless direct voltage converter unit having a first output potential connection and a second transformerless direct voltage converter unit having a second output potential connection. The two direct voltage converter units have a common input potential connection and a common reference potential connection. The first direct voltage converter unit generates, from the input voltage potential, a first output voltage potential on the first output potential connection, which has a higher voltage potential value relative to the reference voltage potential. The second direct voltage converter unit generates, from the input voltage potential, a second output voltage potential on the second output potential connection, which has a lower voltage potential value relative to the reference voltage potential. The device can be cost-effectively produced and provides sufficient safety.
