发本好书，与电力电子的兄弟们分享。Inductors and Transformers For Power ElectronicsThis 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. The
design has many aspects, such as the magnetic core and winding, eddy currents,
insulation, thermal design, parasitic effects, and measurements. A lot of
literature exists concerning those subjects, but the information is spread over
many articles and methods. This book is mainly focused on classical methods
and uses numerical tools such as finite element methods in the background.
We try to give some overview of the basics and technological aspects of the
design. In the different chapters we also describe analytical approximations
based on known analytical solutions, but tuned by finite elements. In most
of the cases, a sufficient accuracy can be obtained and the results are obtained
almost instantaneously, even for graphics using many calculation points. A
fast approximation method is useful as a first step in the design stage, whereas
numerical tools such as finite elements are good in analysis. Specific books
on finite elements exist and the description will not be repeated here.
Some basic introduction on magnetic principles and materials are given
in Chapter 1.
Today power electronics use quite a high switching frequency.
Simple rules
of thumb such as that “the eddy copper current losses are always negligible
when the diameter of the wire is smaller than the penetration depth” are not
true. However, it is clear that the main cause of the eddy current losses is
caused by the presence of high frequency transverse magnetic field components.
This is the base of the fast design method in Chapter 2. The method
is further improved using some corrections for other effects and is embedded
in a decision flow chart of a design procedure. More insight and better
accuracy is provided in the other chapters. We invite the readers to let them
guide by the contents of the book to their specific subjects of interest.
The chapters in the book are organized in a quite independent way with
respective local appendices and references. The general appendices at the
end provide information that is not linked to a specific chapter and can be
used independently.
This work can be seen as complementary information to books on power
electronic circuits. Different levels of complexity are proposed depending on
the available time, the desired accuracy, and the mathematical level of the
designer. 谢谢了，先搜藏了 太贵了啊
