In electrical engineering manufacturing, one of the most important
processes stems from making sure the material used to distribute
the electrical current is safe and operating correctly. The
precarious nature of electricity makes developing innovative
material for advanced safety a high-ranking priority for
researchers. Electrical Insulation Breakdown and Its Theory,
Process, and Prevention: Emerging Research and Opportunities
provides innovative insights into the latest developments and
achievements in high voltage insulation breakdown. Featuring topics
such as nanodielectrics, thermal stability, and transmission
technology, it is designed for engineers, including those that work
with high voltage power systems, researchers, practitioners,
professionals, and students interested in the upkeep and practice
of electric material safety.
If you want to introduce alternative power supplies around the home
and garden or even live totally off-grid in your boat, caravan or
yurt and need a practical introduction to solar power and 12 volt
supplies, here is an essential guide to the subject. Not only will
it save you money, it will show you how to run your lights, laptop,
DVDs and music, and even your tools and household products, from a
simple 12 volt system. Be in control of more of your home's own
energy supply, develop a low impact way of living and be prepared
for power cuts and for power down situations in the future! Do It
Yourself 12 Volt Solar Power begins with a lesson in how
electricity works and the main components of a DIY solar system.
The author uses clear diagrams and terms. There is, of course, more
technical information as the book progresses, but don't worry, this
no-nonsense guide provides a useful, back-to-basics approach for
the layperson. This is a reference book that will help you
trouble-shoot and get the best value for money from what you can
find hidden in the back of the garage. Quirky and humorous, it also
shows you how to make a sun following system using just a bicycle
wheel, a pallet and the motor from a CD player!
This book is a complete guide to the IET Wiring Regulations and the
important changes in Amendment 3 to BS 7671:2008. It provides
comprehensive guidance on all aspects of electrical installation
design, including the Electricity Safety Quality and Continuity
Regulations. Derivations of the requirements are included along
with the relevant formulas, data, installation design calculations,
and examples. The Commentary also includes guidance on related
subjects, such as the prevention of electromagnetic interference,
allowance for harmonic currents and the use of cable armouring.
Master's Thesis from the year 2014 in the subject
Electrotechnology, grade: Master degree, Hohai University (College
of Energy and Electrical Engineering), course: Power Electronics,
language: English, comment: This study employs a buck ZCS (PWM)
converter and develops a novel soft-switching approach for charger
batteries. This thesis presents technique for battery charger to
achieve efficient performance in charging shaping, minimum low
switching losses and reduction in circuit volume. The operation of
circuit charger is switched with the operation of
zero-current-switching, resonant components and appends the
topology of dc-dc buck. The proposed novel dc-dc battery charger
has advantages with the simplicity, low cost, high efficiency.,

This thesis presents technique for battery charger to achieve
efficient performance in charging shaping, minimum low switching
losses and reduction in circuit volume. The operation of circuit
charger is switched with the operation of zero-current-switching,
resonant components and appends the topology of dc-dc buck. The
proposed novel dc-dc battery charger has advantages with the
simplicity, low cost, high efficiency and the behavior of easy
control under the ZCS condition accordingly reducing the switching
losses. The detailed study of operating principle and circuit
design consideration is performed. A short survey of battery
charging system, capacity demand & its topological is also
presented. In order to compute LC resonant pair values in
conventional converter, the method of characteristic curve is used
and electric function equations are derived from the prototype
configuration. The efficient performance of charging shaping is
confirmed through the practical examines and verification of the
results is revealed by the MATLAB simulation. The efficiency is
ensured about 89% which is substantially considere
Master's Thesis from the year 2012 in the subject
Electrotechnology, grade: 9.36, West Bengal University of
Technology, course: M.TECH IN ADVANCE COMMUNICATION, language:
English, comment: this research was performed during my M.Tech
project. Further research is going on and i hope to reach to my
goal regarding this topic., abstract: Advanced developments that
were made recently in the field of Silicon (Si) semiconductor
technology have allowed it to approach the theoretical limits of
the Si material. However there are latest power device requirements
for many applications that cannot be handled by the present
Si-based power devices. These requirements include such as higher
blocking voltages, switching frequencies, efficiency, and
reliability. And hence, new semiconductor materials for power
device applications are needed to overcome these limitations. For
high power requirements, wide bandgap semiconductors like Silicon
Carbide (SiC) and Gallium Nitride (GaN) and Gallium Arsenide
(GaAs), which are having superior electrical properties, are likely
to replace Si in the near future. This Study thesis compares the
electrical characteristics of wide-bandgap semiconductors with
respect to Silicon (Si) to verify their superior utility for power
applications and predicts the future of power device semiconductor
materials. This thesis also includes the study that has been
performed regarding the electrical characteristics of high
frequency semiconductor devices in terms of I-V characteristics and
Noise Power Spectral Density (PSD) Analysis with respect to drain
current fluctuation in the semiconductor devices. The semiconductor
devices that are used for this particular thesis are - Metal Effect
Semiconductor Field Effect Transistors (MESFETs) and High Electron
Mobility Transistors (HEMTs).
