Introduces chaos theory, its analytical methods and the
means to apply chaos to the switching power supply
design
DC-DC converters are typical switching systems which have plenty
of nonlinear behaviors, such as bifurcation and chaos. The
nonlinear behaviors of DC-DC converters have been studied heavily
over the past 20 years, yet researchers are still unsure of the
practical application of bifurcations and chaos in switching
converters. The electromagnetic interference (EMI), which resulted
from the high rates of changes of voltage and current, has become a
major design criterion in DC-DC converters due to wide applications
of various electronic devices in industry and daily life, and the
question of how to reduce the annoying, harmful EMI has attracted
much research interest. This book focuses on the analysis and
application of chaos to reduce harmful EMI of DC-DC converters.
After a review of the fundamentals of chaos behaviors of DC-DC
converters, the authors present some recent findings such as
Symbolic Entropy, Complexity and Chaos Point Process, to analyze
the characters of chaotic DC-DC converters. Using these methods,
the statistic characters of chaotic DC-DC converters are extracted
and the foundations for the following researches of chaotic EMI
suppression are reinforced. The focus then transfers to estimating
the power spectral density of chaotic PWM converters behind an
introduction of basic principles of spectrum analysis and chaotic
PWM technique. Invariant Density, and Prony and Wavelet analysis
methods are suggested for estimating the power spectral density of
chaotic PWM converters. Finally, some design-oriented
applications provide a good example of applying chaos theory in
engineering practice, and illustrate the effectiveness on
suppressing EMI of the proposed chaotic PWM.
* Introduces chaos theory, its analytical methods and the means
to apply chaos to the switching power supply design
* Approaches the subject in a systematic manner from analyzing
method, chaotic phenomenon and EMI characteristics, analytical
methods for chaos, and applying chaos to reduce EMI
(electromagnetic interference)
* Highlights advanced research work in the fields of statistic
characters of nonlinear behaviors and chaotic PWM technology to
suppress EMI of switching converters
* Bridges the gap between numerical theory and real-world
applications, enabling power electronics designers to both analyze
the effects of chaos and leverage these effects to reduce EMI
