Abstract:
|
This paper presents the analysis and design of a
sliding-mode control of a boost converter operating in continuous
conduction mode that minimizes the inrush current and provides
output voltage regulation in front of input voltage perturbations
and load changes. The analytical expression of the inrush current
is obtained, and the conditions to minimize the current peak are
derived. The resulting controller is implemented analogically and
employs two switching surfaces. Namely, one surface is combined
with the conventional auxiliary diode branch for the start-up,
while another one is used for the voltage regulation in steady state.
Experimental results are in perfect agreement with the theoretical
predictions. |
