Claim:
1. An interleaved LLC convertor, comprising: an even number of LLC circuits connected in parallel; and a plurality of windings with the same quantity as that of the LLC circuits, each of the windings having a first terminal and a second terminal, wherein: all first polarization terminals of the LLC circuits at a DC output side together constitute a first output terminal; all the first terminals of the windings together constitute a second output terminal; wherein a first group of the plurality of windings is inversely magnetically coupled to a second group of the plurality of windings; wherein the windings of the plurality of windings have the same inductance, and the first group of the plurality of windings are inversely coupled with the second group of the plurality of windings; wherein each of the windings has an inductance of no more than L wherein respective second polarization terminals of the LLC circuits at the DC output side connect to respective ones of the second terminals of the windings.
