【开始】开关插座的发展依赖予元器件和磁性材料的发展。20世纪70年代后期，随着导体技术的高度发展，高反压快速功率开关管使无工频变压器的开关电源迅速实用化。而集成电路的迅速发展为开关插座控制电路的集成化奠定了基础。陆续涌现出的开关插座的脉冲调制电路，如SG3525和TI494等为开关电源提供了成本低、性能优良可靠、使用泡便的集成控制电路芯片，从而使得开关插座的电路由复杂变为简单。目前，开关插座的输出纹波已降 至1OOmv以下，射频干扰和电磁干扰也被抑制到很低的水平上。总之，随着电力电子技术的发展，开关插座的缺点正逐步被克服，其优点也得以充分发挥。尤其在当前能源比较紧张 的情况V，开关插座的髙效率能够在节能上做出很大的贡献。正因为开关插座具有这些优点，所以它得到了蓬勃的发展。【结束】<o:p></o:p>
