Performance Analysis of Boost Converter for Constant Voltage Applications Under the Variation of Closed-Loop PI Controller Parameters

Abstract

PI Controller is one of the eminent controller
which holds majority of the applications in industrial purposes.
This paper encompasses an analysis on the performance of PI
controller for DC-DC Boost converter for constant voltage
application where codifications of gains of PI controller are done
in terms of natural frequency and damping factor. The converter
has been designed to operate in continuous conduction mode and
the voltage mode control strategy has been proposed by using
pulse width modulation (PWM) with the PI controller. A set of
gain parameters of PI controller can be selected to obtain the
output of the PI controller with low rise time, quick settling time
and also with more stability features. The effectiveness of this
boost (or step up) converter with different set of PI controller
gains
has been verified through simulation where
MATLAB/Simpower is used as the utensil. All the simulation
results intrinsically emphasized on efficient performance of the
proposed control strategy.
