Pulse-width Modulated DC-DC Power Converters (PDF)

This book studies switch-mode power supplies (SMPS) in great
detail. This type of converter changes an unregulated DC voltage
into a high-frequency pulse-width modulated (PWM) voltage
controlled by varying the duty cycle, then changes the PWM AC
voltage to a regulated DC voltage at a high efficiency by
rectification and filtering. Used to supply electronic circuits,
this converter saves energy and space in the overall system.

With concept-orientated explanations, this book offers
state-of-the-art SMPS technology and promotes an understanding of
the principle operations of PWM converters, as well as enabling the
readers to evaluate their characteristics. Design-orientated
analysis (including a steady-state analysis for both continuous and
discontinuous conduction modes) and numerous real-world practical
examples (including circuit models of the PWM converters)
demonstrate how to design these from scratch.

The book provides an in-depth presentation of topologies of PWM
DC-DC power converters, voltage- and current-mode control of PWM
DC-DC power converters, considers power losses in all
components, device stresses, output voltage ripple, converter
efficiency and power factor correction (PFC). It also
includes extensive coverage of the following:

* topologies of high-efficiency switching-mode PWM and
soft-switching DC-DC power converters;

* DC voltage transfer functions (conversion ratios), component
values, losses, efficiency, and stresses;

* small-signal averaged circuit models;

* current-mode and voltage-mode feedback controls;

* metal-oxide-semiconductor field-effect power transistors
(MOSFETs);

* silicon (Si) and silicon carbide (SiC) power semiconductor
devices. Before now, there has been no book that covers silicon
carbide devices.

Pulse-width Modulated DC-DC Power Converters is a
comprehensive textbook for senior undergraduate and graduate
students in the areas of electrical, electronics, and
telecommunications engineering. It includes end-of-chapter
review questions, problems, and thorough summaries of the key
concepts to aid learning, and a Solutions Manual is
available for professors. Scientists and practicing design
engineers working with SMPS, within such applications as computers,
telecommunications, industrial systems, automobile
electronics, medical equipment, aerospace power technology, and
radars (amongst others) will also find this text insightful.
