This book addresses the challenges of designing high performance analog-to-digital converters (ADCs) based on the “smart data converters” concept, which implies context awareness, on-chip intelligence and adaptation. Readers will learn to exploit various information either a-priori or a-posteriori (obtained from devices, signals, applications or the ambient situations, etc.) for circuit and architecture optimization during the design phase or adaptation during operation, to enhance data converters performance, flexibility, robustness and power-efficiency. The authors focus on exploiting the a-priori knowledge of the system/application to develop enhancement techniques for ADCs, with particular emphasis on improving the power efficiency of high-speed and high-resolution ADCs for broadband multi-carrier systems.

Vehicles are intrinsically linked to our lives. This book covers all technical details of the vehicle electrification process, with focus on power electronics. The main challenge in vehicle electrification consists of replacing the engine-based mechanical, pneumatic, or hydraulic ancillary energy sources with electrical energy processed through an electromagnetic device. The book illustrates this evolutionary process with numerous series-production examples for either of body or chassis systems, from old milestones to futuristic luxury vehicles. Electrification of ancillaries and electric propulsion eventually meet into an all-electric vehicle and both processes rely heavily on power electronics. Power electronics deals with electronic processing of electrical energy. This makes it a support technology for the automotive industry. All the automotive visions for the next decade (2020-2030) are built on top of power electronics and the automotive power electronics industry is expected at 15% compound annual growth rate, the highest among all automotive technologies. Hence, automotive power electronics industry is very appealing for recent and future graduates. The book structure follows the architecture of the electrical power system for a conventional engine-based vehicle, with a last chapter dedicated to an introduction onto electric propulsion. The first part of the book describes automotive technologies for generation and distribution of electrical power, as well as its usage within body systems, chassis systems, or lighting. The second part explores deeper into the specifics of each component of the vehicle electric power system. Since cars have been on the streets for over 100 years, each chapter starts with a list of historical achievements. Recognizing the engineering effort span over more than a century ennobles the R&D efforts of the new millennium. Focus on history of electricity in vehicle applications is another attractive treat of the book.The book fills a gap between books targeting practical education and works sharing advanced academic vision, offering students and academics a quick tour of the basic tools and long-standing infrastructure, and offering practicing engineers an introduction on newly introduced power electronics-based technologies. It is therefore recommended as a must-have book for students and early graduates in automotive power electronics activities.

This book addresses topics specific to the application of power electronics to telecom systems. It follows the power flow from national grid down to the last low-voltage high current requirement of a processor. Auxiliary equipment requirements, such as uninterruptible power supplies, storage energy systems, or charging systems, are explained, along with peculiar classification or suggestions for usage. The presentation of each telecom power system is completed with a large number of practical examples to reinforce new material.

The Third Edition of Switching Power Converters goes beyond the design and analysis of conventional power converter circuits to discuss the actual use of industrial technology, covering facets of implementation otherwise overlooked by theoretical textbooks. This edition uniquely presents the historical and market evolution of each technology, allowing the reader to follow trends. Power electronics represents a mature technology, with a variety of products concurrent on the market, designed and launched from the 1990s to 2020s. The theoretical aspects presented in the book are supported with many examples, diligently exemplifying this market complexity. It highlights advancements in new semiconductor devices and packaging technologies, design for reliability, or computer utilization in the design, development, and validation of new technical solutions. It also examines all of the multidisciplinary aspects of medium- and high-power converter systems, including basic power electronics, digital control and hardware, sensors, analog preprocessing of signals, protection devices and fault management, and pulse width modulation (PWM) algorithms.Similar to the previous two editions, the Third Edition of Switching Power Converters remains the go-to-book for understanding all aspects related to the PWM used in the control of power converters. This book is one of the most comprehensive presentations of PWM algorithms, with illustrations of practical results for optimization or implementation on each analog, software, digital hardware, or Gbit flash memory platform.

"Authentic characters and real emotions pull the reader into this unforgettable story."--Miriam Franklin, author of Extraordinary and Call Me SunflowerIt was never supposed to happen ...Twelve year old Rylee has always based her self-worth on the fact that her dad's a highly respected fireman. So what happens when her best friend takes part in a reckless prank that leaves her dad paralyzed, effectively destroying his firefighting career? It's easy for Rylee to place the blame squarely on her best friend's shoulders, but nearly impossible for her to admit her own role in the tragedy. Can she ever find a way to make it up to her dad--to restore not only his, but her own happiness and self-respect?Or is it one of those mistakes that's simply too big to fix?"Highly recommend The Hidden Power of Dandelions for grades 5 and up."--Collabookation

A compelling and visceral story that touches the depths of human hearts. Based on a true encounter by the author, H.O.WARD, presents his character Doris as a homeless vagabond on the streets of London in 1966, where she has the misfortune to fall ill and taken to hospital by her street friend Harry. It is Harry who continues the story of Doris, a tender and caring Queen Alexandra Nurse, telling of her journey through military training in Inverarary, Scotland, her experience of war torn Italy in Anzio, and her romance in Florence, before her forced return to London, England. As with all lives, they should not be judged on the merits of the surroundings in which the person is first encountered, but by the complete understanding and quality of the person, if they should then be judged at all. Read what can only be described as a sensitive walk through the life of a lovely lady, with its highs and heart-wrenching lows.

"Doris er ingen kvinne. Den absurde tanken på at noen en gang skal omtale henne som dame, kan få henne til å bryte ut i høy, hånlig latter. Doris vet hva hun er. Folk må ikke tro at hun ikke skjønner at de betrakter henne, her hun står og ruver midt i glaningen på yachtens tak, stygg og deilig, det avhenger av hvem som ser". Den 14-årige Doris og hennes far Roy Arne Holmås er på ferie et sted langs Norges vestkyst i en yacht på over femti fot, også den kalt Doris. Doris og faren har latt moren Bella og resten av reisefølget sitt i stikken og seiler tilsynelatende planløst rundt på havet. Tenåringen Doris bærer med seg motvilje og ambivalens på reisen, både mot foreldrene og mot livet på sjøen, mens hun jakter på mobildekning og drømmer om gjensynet med sin tretten år eldre flamme, Jimmy. Hvilke planer har egentlig den uforutsigbare faren hennes? Hvor skal de? Og hvor lenge har han tenkt at de skal være på reise? "Doris" er en skarp skildring av tenåringslivet og et far-datter-forhold i ubalanse, på samme tid humoristisk og sår. Det er en varm og nådeløs beretning om å være under kontinuerlig oppsyn og om til stadighet å ha et blikk utenfra på seg selv.
