电源技术 DN1011 简单高效率隔离型反激式电源
 
While simplicity and high effi ciency (for cool running) areno longer optional features in isolated power supplies, itis traditionally diffi cult to achieve both. Achieving higheffi ciency often requires the use of advanced topologiesand home-brewed secondary synchronous rectifi cationsch ...
VHDL/FPGA/Verilog DDR SDRAM控制器的VHDL源代码
DDR SDRAM控制器的VHDL源代码，含详细设计文档。
The DDR, DCM, and SelectI/O&#8482 features in the Virtex&#8482 -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Dig ...

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC se ...

模拟电子 LTC1099基于PC的数据采集板实现
A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Tur ...
