Step-up bipolar transformer rectifier without common mode ripple

Abstract:

A multi-phase transformer. The multi-phase transformer includes a single rectifier; and a plurality of groups of windings connected to the single rectifier. Each one of the plurality of groups of windings comprises: a corresponding plurality of primary windings having a first output voltage; a corresponding plurality of secondary windings having a second output voltage; and a corresponding plurality of tertiary windings having a third output voltage that is higher than the second output voltage.
