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.

First claim

We claim:

1. A multiphase DC-DC converter comprising:
a multiphase transformer having a plurality of input voltage terminals;
shuffle circuitry coupled to the multiphase transformer, the shuffle circuitry:
assign a first phase, to a first terminal of the plurality of input voltage terminals;
assign a second phase, to a second terminal of the plurality of input voltage terminals if a total number of number of phases is odd;
assign a third phase to the second terminal of the…
