The objective of this book is to acquaint the reader with explosive driven
pulsed power devices, theory and applications. This includes those devices
that convert the chemical energy stored in high explosives into electrical
energy and that use shock waves generated by the explosives to release
the energy stored in ferromagnetic or ferroelectric materials in the form of
electrical energy. The reader might well ask why one should use explosive
driven pulsed power for any application, since it is inherently single shot in
The serious challenge facing the world today, in obtaining enough energy for growing population and in controlling the carbon emission caused by fossil fuel use, calls for nuclear energy as an alternative power source. This book presents research work and technical experience from several power plants and research institutions around the world from practical prospective.
Positioning systems in general have their most basic form, and also the most complex, in the human being. The brain serves as the summing network that accepts the command for a desired motion or position, the musculatory system serves as the power source or prime mover to cause motion to take place, and the sensory system, such as the eyes, determines the present position. In general, these three things—the brain, the muscles, and the eyes—are analogues to the three basic parts of any positioning system....
Power electronics is the technology of processing and controlling the flow of electric energy
by supplying voltages and currents in a form that is optimally suited to the end-user’s
requirements .Atypical block diagram is given in Figure 1.1 . The input power can be
either AC and DC sources. A general example is one in which the AC input power is from
the electric utility. The output power to the load can be either AC and DC voltages. The
power processor in the block diagram is usually called a converter. Conversion technologies
are used to construct converters.
A transmission or gearbox provides speed and torque conversions
from a rotating power source to another device using gear ratios,
including for a motor vehicle partly because of the limitations of
internal combustion engines.Usually found near motors of some sort, gearboxes are used to
reduce the load on the motor by using the motor's own momentum
to keep it turning.
Engineering for sustainability is an emerging theme for the twenty-first century,
and the need for more environmentally benign electric power systems is a critical
part of this new thrust. Renewable energy systems that take advantage of
energy sources that won’t diminish over time and are independent of fluctuations
in price and availability are playing an ever-increasing role in modern power
Crystal radio receiver - also known as crystal receiver - radio is a simple yet very common in the early days of radio industry. No batteries or other power source to an activity that uses the power received from radio waves through a very long wire antenna and high. In Vietnam, formerly known as Galen
This is a comprehensive textbook for the new trend of distributed power generation systems and renewable energy sources in electric power systems. It covers the complete range of topics from fundamental concepts to major technologies as well as advanced topics for power consumers.
With technology advancements in semiconductor devices such as insulated gate
bipolar transistors (IGBTs) and gate commutated thyristors (GCTs), modern highpower
medium voltage (MV) drives are increasingly used in petrochemical, mining,
steel and metals, transportation and other industries to conserve electric energy,
increase productivity and improve product quality.
Although research and development of the medium voltage (2.3 KV to 13.8 KV)
drive in the 1-MW to 100-MW range are continuously growing, books dedicated to
this technology seem unavailable.
With the proliferation of electronic loads such as computers, the incidence of power quality-related problems is growing. As a result, the uninterruptible power supply (UPS) market has grown signiﬁcantly in the last few years. What follows is an overview of UPS functions and descriptions of common types of UPSs and backup power sources.
16.1 UPS Functions
The primary purpose of a UPS is to provide conditioned, continuous power to its load. Another UPS function that is of growing importance in today’s market is system integration, or the...
Today’s wind energy industry is at a crossroads. Global economic instability has threatened
or eliminated many financial incentives that have been important to the development of
specific markets. Such economic sponsorship of energy generation is not unique to
renewables; fossil based sources are also subsidized in many different countries. However,
for a technology like wind energy whose markets are still developing, incentives can be
critical for industry growth.
Nuclear power approximately supplies a sixth of the world's electricity and considers
as the major source of "carbon-free" energy today. With growing concerns aboutglobal
warming, it is not surprising that governments and power providers around the world
are considering building a substantial number of additional nuclear power plants.
These plants have demonstrated remarkable reliability and efficiency with the help of
extensive research work and sharing operational practical experience.
This handbook is a continuation of our efforts to gather state-of-the-art research on
power systems topics in Operations Research. Specifically, this handbook focuses
on aspects of power system networks optimization and is, as such, a specialization
of the broader “Handbook of Power Systems I & II,” published by Springer in 2010.
For decades, power systems have been playing an important role in humanity.
Industrialization has made energy consumption an inevitable part of daily life.
There is an upward trend that human activities involve more electric power nowadays
and for years to come. And we will soon be facing shortage of electricity supply if we
rely solely on non-renewable power generation from fossil fuels such as coals.
Renewable energy generation has proven effective in meeting the demand.
The wind is a free, clean, and inexhaustible energy source. It has served humankind well for many centuries by propelling ships and driving wind turbines to grind grain and pump water. Denmark was the ﬁrst country to use...

ADC’s new Midspan Power-over-Ethernet (PoE) Controller provides a flexible way to power IP
telephony and other applications over a local area network. The IEEE 802.3af-compliant power source
ensures reliability of service for Ethernet devices such as VoIP telephones, wireless access points,
security cameras, etc. ADC’s midspan PoE controller also eliminates the need for installation of local
power at the device, saving time and money.
