电源技术 智能电网安全保护
Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. ...
电源技术 优化输电线路 精确测量电压驻波比(VSWR)
Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss andreflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line imperfections. Thistutorial defines VSWR and explains how it is calculated. Finally, an antenna VSWR ...
电源技术 智能电表和智能电网手册
Abstract: Investment in smart meters and smart grid end equipment continues to grow worldwide as countriestry to make their electric delivery systems more efficient. However, as critical as the electric deliveryinfrastructure is, it is normally not secured and thus subject to attack. This article ...
电源技术 低电压FPGA的高性能开关电源解决方案
 
The core voltages for FPGAs are moving lower as a resultof advances in the fabrication process. The newest FPGAfamily from Altera, the Stratix® II, now requires a corevoltage of 1.2V and the Stratix, Stratix GX, HardCopy®Stratix and CycloneTM families require a core voltage of1.5V ...
电源技术 手持式高功率电池充电器
 
As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, ...
电源技术 太阳能电池板电池充电技术手册
 
Advances in low power electronics now allow placementof battery-powered sensors and other devices in locationsfar from the power grid. Ideally, for true grid independence,the batteries should not need replacement, but instead berecharged using locally available renewable energy, suchas so ...
电源技术 高效率,高密度,高电流应用的多相转换器
 
As logic systems get larger and more complex, theirsupply current requirements continue to rise. Systemsrequiring 100A are fairly common. A high current powersupply to meet such requirements usually requires parallelingseveral power regulators to alleviate the thermalstress on the individ ...
单片机编程 DS8005评估套件入门
Abstract: This application note describes how to build, debug, and run applications on the on-board MAXQ622microcontroller to interface with the DS8005 dual smart card interface. This is demonstrated in both IAREmbedded Workbench and the Rowley CrossWorks IDE, using sample code provided with the k ...
单片机编程 基于HITAG读写芯片HTRC110的读写设备设计
Designing read/write device (RWD) units for industrial RF-Identification
applications is strongly facilitated by the NXP Semiconductors HITAG
Reader Chip HTRC110. All needed function blocks, like the antenna
driver, modulator demodulator and antenna diagnosis unit, are integrated
in the HTRC11 ...
单片机编程 MAXX9257 MAX9258芯片可编程SerDes持续时间计算
The MAX9257/MAX9258 programmable serializer/deserializer (SerDes) devices transfer both video data and control signals over the same twisted-pair cable. However, control data can only be transmitted during the vertical blank time, which is indicated by the control-channel-enabled output (CCEN) sig ...
