简介：介绍了集成输入滤波电感和倍流电感的推挽正激变换器。这种变换器具有平滑的输入电流，简单的主电路，小的体积，高的效率和功率密度。分析了它的工作过程，对于磁集成部分给出了Z参数模型，并利用该模型，对变换器进行了PSPICE仿真。最后通过试验验证了仿真结果。

简介：本文对电力滤波装置系统设计及设备设计应遵循的一般原则与若干技术问题进行了探讨。

简介：我家里的多媒体音箱早就被废弃了,一是信噪比低,丝丝的本底噪音和电脑主机风扇声互相呼应好不热闹;二是听不完一张唱片就耳根发麻,需要不断减轻音量,直到关掉才觉得耳朵清静,舒坦多了。烦恼就在这里,耳根清静了,但没有音乐很单调又乏味,用耳机吧,我又怕头皮发麻,又不太喜欢那种空间有点闭塞、耳朵皮受压、空气不流通的感觉。但也没办法,更多的时间是用Discman胡乱插一副耳塞对付着。

简介：提出一种新的，已获专利的多相交叉升压电路拓扑（专利申请号No.00257426&00130365),使用这种多相电路拓扑，可将电力电子产品的有源功率因数校正的输出功率扩展至2－4kW,以满足IEC1000－3－2标准的规定，多相交叉升压式的有源功率因数校正技术具有输出功率大，电路简单，成本低等优点，对双端推挽式升压电路的主功率级和控制器做了分析，并给出了输了功率为2kW样机的实验结果。
