技术资料 600w變壓器计算
那么我们可以进行如下计算：1，输出电流Iout=Pout/Udc=600/400=1.5A2，最大输入功率Pin=Pout/η=600/0.92=652W3，输入电流最大有效值Iinrmsmax=Pin/Umin=652/85=7.67A4，那么输入电流有效值峰值为Iinrmsmax*1.414=10.85A5，高频纹波电流取输入电流峰值的20%，那么Ihf=0.2*Iinrmsmax=0.2*10.85=2.17A6，那么输入电感电流最大 ...
技术资料 AL422B
The AL422B consists of 3M-bits of DRAM, and is configured as 393,216 words x 8 bit FIFO (first
in first out). The interface is very user-friendly since all complicated DRAM operations are already
managed by the internal DRAM controller.
Current sources of similar memory (field memory) in the market ...

书籍 Pro Arduino
Since its release, Arduino has become more than just a development platform; it has become a culture built around
the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has
opened hardware development by making the starting skills easy to obtai ...
书籍 Power Over Ethernet
December 2007, San Jose, California: It seems a long time ago.
I walked into a big networking company to head their small
Power over Ethernet (PoE) applications team. Surprisingly,
I hardly knew anything about PoE prior to that day, having been a
switching-power conversion engineer almost all my lif ...
技术资料 移植到Symbian平台C-C.开放移动开发.rar
I originally started writing this book as part of the Symbian Press Technology
series back in May 2008. Since that time, a lot has changed in
the mobile software world, particularly for those working with Symbian
devices. The book you now hold in your hands is published by the
Symbian Foundation usi ...
技术资料 基于STM32单片机控制的智能水杯设计
本设计介绍了一种基于STM32单片机控制的智能水杯,可利用插口式电源或无线充电底座为加热器提供能量,并在达到某种饮品所需温度时进行保温。水杯内置充电电池,可选用USB接口或无线充电。在水杯内部设置无线模块,用户利用手机App与水杯进行匹配进行加热操作,加热完后水杯会通过手机App和液晶显示屏实时反馈液体温度,通过指示灯 ...
