ABSTRACT: KY Boost Converter, a modern invention in the field of
non-isolated DC-DC boost converter is identified for minimum voltage ripple. KY
boost converter is the com- bination of KY converter and traditional boost converter. Such a
converter has con- tinuous input and output inductor current, different from the traditional
boost con- verter. And hence this converter is very suitable for very low-ripple
applications. The Particle Swarm Optimization (PSO) based controller,
FUZZY based controller and open loop KY boost converter are designed in
MATLAB/Simulink model. The simu- lated results show a reduction in output ripple from 1.18 V of the existing open
loop KY boost converter output to 0.54 V in the FUZZY logic controlled converter out- put. Further reduction in
output ripple to 0.29 V is
achieved in the proposed PSO based converter. The simulated results also show
the variation of switching pulses based on the different existing and proposed
method.
