COMPOSITE MAGNETIC COMPONENT AND SWITCHING POWER SUPPLY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce the number of components in a circuit requiring a reactor and a transformer.

SOLUTION: A composite magnetic component 100 comprises: a reactor including a core 16 for reactor and a reactor winding 18 wound around the core 16 for reactor; a core 10 for transformer arranged to face both ends of the core 16 for reactor via a magnetic gap 20 to configure a round magnetic circuit; a primary winding 12 of the transformer wound around the core 10 for transformer while being divided at a plurality of places symmetrical spatially with respect to the core 16 for reactor; and a secondary winding 14 of the transformer wound around the core 10 for transformer while being divided at a plurality of places symmetrical spatially with respect to the core 16 for reactor.
