多相交错DC-DC变换器中负耦合电感的数学建模与多目标优化

To optimize the converter efficiency, footprint and volume of magnetic devices simultaneously, this article proposes a mathematical modeling and multiobjective optimization method based on multiphase negative-coupled inductor (NCI) in interleaved dc–dc converter, and elaborates on the specific details by taking interleaved buck converter (IBC) and four-phase NCI as an example. First, flux cancella...
