Abstract (en)
[origin: WO2014056661A2] The invention relates to a device (V) for voltage conversion having a first, transformerless direct voltage converter unit (GW1) having a first output potential connection (Pa1) and a second transformerless direct voltage converter unit (Gw2) having a second output potential connection (Pa2). The two direct voltage converter units (GW1, GW2) have a common input potential connection (Pe) and a common reference potential connection (Pb). The first direct voltage converter unit (GW1) generates, from the input voltage potential (Φe), a first output voltage potential (Φa1) on the first output potential connection (Pa1), which has a higher voltage potential value relative to the reference voltage potential (Φb). The second direct voltage converter unit (GW2) generates, from the input voltage potential (Φe), a second output voltage potential (Φa2) on the second output potential connection (Pa2), which has a lower voltage potential value relative to the reference voltage potential (Φb). The device can be cost-effectively produced and provides sufficient safety.
