Abstract |
A hybrid magnetic approach, consisting of merging two different magnetic core properites such as ferrite and ironpowder cores together, is an effective solution for power converter applications. It can provide similar magnetic properties to that of magnetic powder cores but showing less copper loss than powder cores. Additionally, the relatively large inductance at low loading current is an excellent way to minimize total power loss, achieving high efficiency. In order to prevent ferrite core saturation, placing an effective air gap within the ferrite core is a key method to obtain optimum hybrid magnetic performance. |
