基于UCC28019的PFC电路设计
<p>为设计高效率、低损耗的PFC电路,本文基于UCC28019进行电路设计。以UCC28019输出的PWM波形来控制Boost升压斩波为核心电路,使电路中的电容交替地充放电、电感交替的储存和释放能量,最后实现在输入AC20V~24V电压情况下稳定输出DC38V。测试结果表明,系统实现效率为95%左右,电压调整率小于1%,电源功率因数0.99。交流输入电压为19.0-25.8 V时,输出直流电压稳

Line+Loss+Analysis
It has been over a decade since the Chinese publication of Line Loss in Electric Power Systems. To keep pace<br />
with technological developments, I started a revision as early as 2002, following the

cognitive radio and signal classification receivers. The approach under study is the N-path filte
Mobile+Channel+Characteristics
At the macroscopic level of system layout, the most important issue is path loss. In the<br />
older mobile radio systems that are limited by receiver noise, path loss determines SNR and<br />

This book addresses two aspects of network operation quality; namely, resource<br />
management and fault management.<br />
Network operation quality is among the functions to be fulfilled in order to
Dynamic+Channel+Acquisition
Multiuser multiple-input-multiple-output (MU-<br />
MIMO) systems are known to be hindered by dimensionality<br />
loss due to channel state information (CSI) acquisition overhead.<br />

择PCB板材必须在满足设计需求和可量产性及成本中间取得平衡点。设计需求包含电气和机构这两部分。通常在设计非常高速的PCB板子(大于GHz的频率)时这材质问题会比较重要。例如，现在常用的FR-4材质，在几个GHz的频率时的介质损(dielectric loss)会对信号衰减有很大的影响，可能就不合用。就电气而言，要注意介电常数(dielectric constant)和介质损在所设计的频率是否合用。
