摘要： Aspects of direct current (DC)-DC converters with an integrated matrix transformer and multiphase current doubler rectifiers are described. In some examples, a DC-DC converter can include a matrix transformer that has multiple magnetically integrated transformer components that are magnetically integrated using transformer components that share a top plate and a bottom plate. A multiphase current doubler rectifier can include multiple synchronous rectifiers corresponding to the plurality of transformer components of the matrix transformer.

摘要： Power converters with current doubler rectifier output stages, current doubler rectifier output stages, and integrated transformers for current doubler rectifier output stages and related output stages are described. In one example, a power converter includes a switched bridged input stage and a current doubler rectifier output stage comprising an integrated transformer. The integrated transformer of the current doubler rectifier output stage includes magnetic cores. A primary winding and a secondary winding of the integrated transformer extend around each of the plurality of magnetic cores, and the integrated transformer further includes a coupling winding that extends around each of the plurality of magnetic cores to provide magnetic integration among the plurality of magnetic cores through an electrical coupling. The current doubler rectifier output stage relies upon magnetizing inductance of the integrated transformer to realize the function of inductors, and the integrated transformer current doubler rectifier does not include separate inductors.
