Abstract

The buck, buck-boost and boost converter, are
the most popular types of DC-DC converters. The input/output charachteristics of
these converters operating in Continuous Current Mode (CCM) is the object of
considerations in this paper. Calculation of input/output impedance is done
with the aid of MATLAB programming since the manual extraction, i.e.
pencil-and-paper analysis, of input/output characteristics is cumbersome and
error prone. This paper can be used as a tutorial on the extraction of
input/output impedance of DC-DC converters.

Keywords
