Power electronic devices

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.

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....

Electrical consumption, especially direct or variable frequency currents, has strongly increased over 50 years in industry. This situation explains the growth of power electronics. 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.

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.
