Power Electronics and Energy Conversion Systems is a
definitive five-volume reference spanning classical theory through
practical applications and consolidating the latest advancements in
energy conversion technology. Comprehensive yet highly accessible,
each volume is organised in a basic-to-sophisticated crescendo,
providing a single-source reference for undergraduate and graduate
students, researchers and designers.

Volume 1 Fundamentals and Hard-switching Converters introduces the
key challenges in power electronics from basic components to
operation principles and presents classical hard- and
soft-switching DC to DC converters, rectifiers and inverters. At a
more advanced level, it provides comprehensive analysis of DC and
AC models comparing the available approaches for their derivation
and results. A full treatment of DC to DC hard-switching converters
is given, from fundamentals to modern industrial solutions and
practical engineering insight. The author elucidates various
contradictions and misunderstandings in the literature, for
example, in the treatment of the discontinuous conduction operation
or in deriving AC small-signal models of converters.

Other key features:

* Consolidates the latest advancements in hard-switching
converters including discontinuous capacitor voltage mode, and
their use in power-factor-correction applications

* Includes fully worked design examples, exercises, and case
studies, with discussion of the practical consequences of each
choice made during the design

* Explains all topics in detail with step-by-step derivation
of formulas appropriate for energy conversion courses

* End-of-section review of the learned material

* Includes topics treated in recent journal, conference and
industry application coverage on solutions, theory and practical
concerns

With emphasis on clear explanation, the text offers both a
thorough understanding of DC to DC converters for undergraduate and
graduate students in power electronics, and more detailed material
suitable for researchers, designers and practising engineers
working on the development and design of power electronics. This is
an accessible reference for engineering and procurement managers
from industries such as consumer electronics, integrated circuits,
aerospace and renewable energy.
