| Abstract |
This paper presents results of the analysis and design of a
multi-phase buck converter with integrated filter inductor
when operated with a wide range of voltage conversion
ratios. Included are the analysis of the converter input and
output currents to optimize the required filter capacitors,
the analysis and design of the integrated filter inductor and
results of a state-space controller that provides robust
control of the output voltage for the required wide range of
input voltages and loads ranging from full to no-load
conditions. The influence of the wide range of input voltages
to the operation of the converter is demonstrated. A
prototype converter with four phases and an integrated
filter inductor has been built and tested to verify predictions
from the analysis. |
