摘要
电感与变压器是开关变换器中不可缺少的磁元件,文中介绍其基本原理,并简要叙述某些磁元件的结构、性能与应用,如饱和电感、平面变压器、空心PCB变压器、集成磁元件等,还介绍了压电变压器的原理。
Inductors and transformers are essential magnetic components of switching power converters. The basic principles are introduced. Constructions,performances and applications of some magnetic components are briefly illustrated,including, saturable inductor, planar magnetic component, coreless PCB transformer and integrated etc. The piezo-electric transformer in principle is also introduced.
