  • MEMS+Lorentz+Force+Magnetometers

    Nowadays sensors are part of everyday life in a wide variety of fields: scientific applications, medical instrumentation, industrial field, ...and, last but not least, popular mass production and low-cost goods, like smartphones and other mobile devices. Markets and business behind the field of sensors are quite impressive. A common trend for consumer applications is miniaturization which requires, on one side, a lot of research, development efforts, and resources but, on the other hand, allows costs and final application size reduction. In this scenario scientific community and industries are very ACtive to drive innovation.

  • MEMS-based+Circuits+and+Systems

    Over many years, RF-MEMS have been a hot topic in research at the technology and device level. In particular, various kinds of mechanical Si-MEMS resonators and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The BAW technology has made its way to commercial products for passive RF filters, in particular for duplexers in RF transceiver front ends for cellular communica- tions. Beyond their use in filters, micromachined resonators can also be used in conjunction with ACtive devices in innovative circuits and architectures.

  • Computational+Intelligence

    The large-scale deployment of the smart grid (SG) paradigm could play a strategic role in supporting the evolution of conventional electrical grids toward ACtive, flexible and self- healing web energy networks composed of distributed and cooperative energy resources. From a conceptual point of view, the SG is the convergence of information and operational technologies applied to the electric grid, providing sustainable options to customers and improved security. Advances in research on SGs could increase the efficiency of modern electrical power systems by: (i) supporting the massive penetration of small-scale distributed and dispersed generators; (ii) facilitating the integration of pervasive synchronized metering systems; (iii) improving the interaction and cooperation between the network components; and (iv) allowing the wider deployment of self-healing and proACtive control/protection paradigms.

  • Intelligent Networked Teleoperation Control

    This book describes a unifying framework to networked teleoperation systems cutting across multiple research fields including networked control system for linear and nonlinear forms, bilateral teleoperation, trilateral teleoperation, multilateral teleoperation, cooperative teleoperation, and some teleoperation application examples. Networked control has been deeply studied at the intersection of systems & control and robotics for a long time, and many scholarly books on the topic have been already published. Nevertheless, the approach remains ACtive even in several new research fields, such as bilateral teleoperation, single master and multiple slaves, trilateral teleoperation, and multilateral teleoperation

  • Design for Manufacturability and Statistical

    Design for manufacturability and statistical design encompass a number of activities and areas of study spanning the integrated circuit design and manufacturing worlds. In the early days of the planar integrated circuit, it was typical for a handful of practitioners working on a particular design to have a fairly complete understanding of the manufacturing process, the resulting semiconductor ACtive and passive devices, as well as the resulting circuit - often composed of as few as tens of devices. With the success of semiconductor scaling, predicted and - to a certain extent even driven - by Moore’s law, and the vastly increased complexity of modern nano-meter scale processes and the billion-device circuits they allow, there came a necessary separation between the various disciplines.

  • PFC技術詳解

    PFC基礎知識-PF的定義1功率因數(Power Factor)的定義是指輸入有功功率(p)和視在功率(S)的比值;線性電路功率因數可用Cos表示,為正弦電流與正弦電壓的相位差;但是由于整流電路中二極管的非線性,導致輸入電流為嚴重的非正弦波形,用cosp已不能表示整流電路的功率因數;常規直接整流電路的濾波電容使輸出電壓平滑,但卻使輸入電流變為尖脈沖,并產生高次諧波分量。輸入電流波形變,導致功率因數下降,污染電網,甚至造成電子設備損壞。引入功率因數校正是必要的利用功率因數校正技術可A/全跟蹤交流輸入電壓波形,流輸入電流波形完使輸入電流波形皇純正弦波,并且與輸入電壓波形相位,,此時整流器的貨載可等效為純電阻。根據常用功率因數校正方法可分為有源功率因數校正(APFC)技術與無源功率因數校正(PPFC)技術。它置于橋式整流器與濾波用電解電容器之間,實際上是一種DC-DC變換器。無源功率因數校正是利用電感和電容組成濾波器,對輸入電容進行移相和整形。有源功率因數校正(APFC:ACtive Power Factor Correction),在負載即電力電子裝置本身的整流器和濾波電容之間增加一個功率變換電路,將整流器的輸入電流校正成為與電網電壓同相位的正弦波,消除了諧波和無功電流,因而將電網功率因數提高到近似為1.APFC電路常用拓撲:升壓式(Boost)降壓式(Buck)升/降壓式(Buck/Boost)反激式(Fly back)APFC電路形式:單極式 雙極式單相PFC 三相PFCBoost變換電路是有源功率因數校正器主回路拓撲的極好選擇。優點:輸入電流連續,因而產生低的傳導噪聲和最好的輸入電流波形;缺點:需要比輸入峰值電壓還要高的輸出電壓。
