书籍 Radio Wave Propagation
One of the prerequisites for the development of telecommunication services is the
understanding of the propagation of the waves, either acoustic, electromagnetic,
radio or light waves, which are used for the transmission of information.
In this work, we shall limit ourselves to the study of radio wa ...
书籍 RF Imperfections
The unguided transmission of information using electromagnetic waves
at radio frequency (RF) is often referred to as wireless communications,
the first demonstration of which took place at the end of the 19th cen-
tury and is attributed to Hertz. The technology was, shortly thereafter,
commercialise ...
书籍 Radio Frequency Identification and Sensors
There is an unprecedented enthusiasm for radio frequency
identification (RFID) technologies today. RFID is based on the
exchange of information carried by electromagnetic waves between a
label, or tag, and a reader. This technology is currently in full
economic expansion, which has manifested itself ...
技术资料 基于TMS320F28035芯片为控制核心的空间矢量异步电机变频器
基于TMS320F28035芯片为控制核心的空间矢量异步电机变频器  我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心，通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法，并对其进行了优化。采用检测反电势的方法省去了昂贵的光电编码器，大大节省了成本。同时开创性的研发了自动 ...
