Abstract: A multiphase DC-DC converter is provided that includes a multiphase transformer, the multiphase transformer including a plurality of input voltage terminals and an transformer output voltage terminal, each input voltage terminal associated with a corresponding phase. Each phase is assigned to an input voltage terminal of the plurality of input voltage terminals to minimize a ripple current at the input voltage terminals of the multiphase transformer.
