发明名称 INTERLEAVED LLC CURRENT EQUALIZING CONVERTER
摘要 The present invention discloses an interleaved LLC convertor with current sharing. The interleaved LLC convertor with current sharing comprises: an interleaved LLC circuit, consisting of an even number of LLC circuits connected in parallel; and a plurality of windings with the same quantity as that of the LLC circuits, wherein all first polarization terminals from each of LLC circuits at its DC output side together constitute a first output terminal; all first terminals from each of the windings together constitute a second output terminal; a first half of the plurality of windings surround a magnetic core in a first direction, and a second half of the plurality of windings surround the magnetic core in a second direction; each of the plurality of windings has the same inductance, and the first half of the plurality of windings are inversely coupled with the second half of the plurality of windings; and the second polarization terminal of each LLC circuit at its DC output side connects to a second terminal of one of the windings.
