| Summary: | A fuzzy controller of DC-DC Buck-boost converter is designed and presented in this
project. In order to control the output voltage of the buck-boost converter, the controller
is designed to change the duty cycle of the converter. The mathematical model of buckboost
converter
and
fuzzy
logic
controller
are
derived
to design
simulation
model.
The
simulation
is
developed
on
Matlab
simulation
program.
To verity
the effectiveness
of the
simulation
model,
an experimental
set
up is
developed.
The
buck-boost
circuit
with
mosfet
as
a switching
component
is
developed.
The
fuzzy
logic
controller
to
generate
duty
cycle
of PWM
signal
is
programmed.
The
simulation
and
experimental
results
show
that
the output voltage
of
the buck-boost
converter
can
be
controlled
according
to the
value
of
duty
cycle |
