Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment.
This book is mainly intended for designers and users of magnetic components
in power electronics. It can also be used for didactical purposes. Magnetic
components such as inductors and transformers constitute together with the
control and the semiconductor components, the main parts in the design of
power electronic converters. Some experience teaches that the design of the
magnetic parts is still often done by trial and error. This can be explained by
a (too) long working-in time for designing inductors and transformers.
Within this book the fundamental concepts associated with the topic of power electronic control are covered alongside the latest equipment and devices, new application areas and associated computer-assisted methods.

Power electronic converters (PECs) are static devices, without any movable parts, that convert electric energy of one set of properties into electric energy of another, different set of properties. The properties that are changed by the action of the converter are one or more of the following: number of phases, frequency, and voltage rms (or average, in the DC case) value. Thus any power electronic converter is essentially a transformer in a broad sense. Action of a power electronic converter is illustrated in Fig....
Offering step-by-step, in-depth coverage, the new Third Edition of Power Electronics: Converters, Applications, and Design provides a cohesive presentation of power electronics fundamentals for applications and design in the power range of 500 kW or less. The text describes a variety of practical and emerging power electronic converters made feasible by the new generation of power semiconductor devices. The new edition is now enhanced with a new CD-ROM, complete with PSpice-based examples, a new magnetics design program, and PowerPoint slides.
Power Electronics is the technology associated with efficient conversion, control and conditioning of electric power from its available input into the desired electrical output form. The field of the book is concerned of electrical power processing using electronic devices the key component of which is a switching power converter.
(BQ) Part 2 book "Electronic devices and circuit theory" has contents: BJT and JFET frequency response, linear digital ICs, sinusoidal alternating waveforms, operational amplifiers, Op-Amp applications, power amplifiers, power supplies, oscilloscope and other measuring instruments,...and other contents.
Electrical consumption, especially direct or variable frequency currents, has
strongly increased over 50 years in industry. This situation explains the growth of
At the beginning, when rectifiers replaced DC machines, only diodes and
thyristors were used. Then power transistors appeared and enabled the extension of
smaller power applications for domestic use. New research topics were developed
around converters and power devices.
I have been undertaking the research and practical applications of power
system optimization since the early 1980s. In the early stage of my career, I
worked in universities such as Chongqing University (China), Brunel
University (UK), National University of Singapore, and Howard University
(USA). Since 2000 I have been working for AREVA T & D Inc (USA). When
I was a full - time professor at Chongqing University, I wrote a tutorial on power
system optimal operation, which I used to teach my senior undergraduate
students and postgraduate students in power engineering until 1996.
Energy harvesting from ambient waste energy for the purpose of running low-powered electronics
has emerged during the last decade as an enabling technology for wireless applications.
The goal of this technology is to provide remote sources of electric power and/or to recharge
storage devices, such as batteries and capacitors. The concept has ecological ramifications in
reducing the chemical waste produced by replacing batteries and potential monetary gains by
reducing maintenance costs.
Power electronics is an enabling technology for all electrical and electronic apparatus requiring electric power to drive. Over the past twenty years, the power electronics industry has grown tremendously. Its growth is a result from increasing demand of reliable, eﬃcient, compact and cost eﬀective power supplies for telecommunication, computer, and motor drive industries as well as for medical equipments and military use.
A review of silicon properties is important to understanding silicon components,
in particular modern components such as strained-silicon MOSFETs and heterojunction
bipolar transistors. Several books cover this subject in detail. The objective
of this chapter is to highlight those features that are most important to silicon device
operation and characteristics.
In practice, consumption devices are not only resistive but also reactive and this reactance varies with time. Therefore, grid voltage is not stable and coefficients always change in spite of using Automatic Reactive Power Regulator. To regulate voltage and cosφ in an expected range, it is necessary to change the parameters of regulators as the loads change.
