ABSTRACT
Computers play an important role in the analyzing and designing of modern DC-DC power
converters. is book shows how the widely used analysis techniques of averaging and lineariza-
tion can be applied to DC-DC converters with the aid of computers. Obtained dynamical equa-
tions may then be used for control design.
e book is composed of two chapters. Chapter 1 focuses on the extraction of control-
to-output transfer function. A second-order converter (a buck converter) and a fourth-order
converter (a Zeta converter) are studied as illustrative examples in this chapter. Both ready-to-
use software packages, such as PLECS
®
and MATLAB
®
programming, are used throught this
chapter.
e input/output characteristics of DC-DC converters are the object of considerations
in Chapter 2. Calculation of input/output impedance is done with the aid of MATLAB
®
pro-
gramming in this chapter. e buck, buck-boost, and boost converter are the most popular types
of DC-DC converters and used as illustrative examples in this chapter.
is book can be a good reference for researchers involved in DC-DC converters dynamics
and control.
