In this paper, a dc-dc buck converter with digital PIcontrolled is analyzed and designed considering all design
parameters such as inductance current variation, output voltage
ripple etc. The designed dc-dc buck converter provides stable
output voltage against to load changes and output voltage
variations. Buck converter control method relies on voltage mode
controlled PWM (Pulse width Modulation) with digital PI
(Proportional Integral) controller. The design criteria, operating
mode selection, suitable material selection, etc. of low cost and
high-performance buck converter are explained in detail. Finally,
the designed converter is carried out experimentally and the
experimental results shows the effectiveness of designed converter
under different load profiles.
