摘要： An electromagnetic connector is disclosed that is configured to form a first magnetic circuit portion comprising a first core member and a first coil disposed of the first core member. The electromagnetic connector is configured to mate with a second electromagnetic connector, where the second electromagnetic connector is configured to form a second magnetic circuit portion comprising a second core member and a second coil disposed of the second core member. The first core member and the second core member are configured to couple the first coil to the second coil with a magnetic circuit formed from the first magnetic circuit portion and the second magnetic circuit portion when the electromagnetic connector is mated with the second electromagnetic connector. The magnetic circuit is configured to induce a signal in the first coil when the second coil is energized.

摘要： Provided are an inversely coupled inductor and a power module. The inversely coupled inductor includes a magnetic core, a first winding and a second winding, where a first passage is formed in the magnetic core; a part of the first winding and a part of the second winding pass through the first passage, and the first winding crosses with the second winding outside the first passage. The power supply module includes the above inversely coupled inductor, which is in turn stacked on, and electrically connected to, the packaged chip module. By arranging the two windings to cross with each other on the outside of the first passage of the magnetic core, the same type terminal (such as input pins or output pins) of the inversely coupled inductor can be located on the same side.

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.

摘要： A transformer includes a magnetic structure and a set of coils. The magnetic structure includes a top member, a bottom member, and a plurality of legs extending between the top member and the bottom member. The plurality of legs include two outer legs. The set of coils is wound about the two outer legs of the magnetic structure and electrically coupled in series. In other examples, the magnetic structure includes a middle member positioned between the top member and the bottom and extending between the two outer legs. In such examples, a second set of coils is wound about the two outer legs of the magnetic structure and electrically coupled in series. Other example transformers and power converters such as multiphase interleaved power converters having transformers are also disclosed.
