摘要： A DC-DC converter having a primary side comprising at least three actively switched primary voltage bridges with several active switches for converting a DC input voltage into primary alternating voltages for each of the primary voltage bridges, and having a secondary side comprising at least three actively switched secondary voltage bridges with several active switches for converting the secondary alternating voltages into a shared DC output voltage for each of the secondary voltage bridges. The primary and secondary alternating voltages are each shifted by a phase angle φ with the periods T, and each of the primary and secondary voltage bridges is coupled to an appertaining phase via one or more transformers.
