Abstract
The following studdy was carried out in order to
assses quantitatively the performannce of the buck--boost converter
whhen used as swiitch-mode audio amplifier. It comprises of, to
beggin with, the de limitation of design criteria bassed on the state of-the-art solution, which is based in a differential mode buckbased
amplifier with a boost converter as power supply. The
averaged switch modelling of the differential mode current
bidirectional topology is also used, in order to analyze the steady
state and frequency-wise behaviour of this converter and
parameterize it to meet the design criteria. Next, several
piecewise-linear siimulation resultss are shown with detail enough
to emphasize the features of the converter. A simple prototype is
implemented to verify the main predicted features. Presently no
previous publicat ion could be found containing a thorough
analysis of this topology in such configuration when applied for
audio.
