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.
Highlights
For the function of the power supply using the low voltage battery, analog circuits, such as radio-frequency (RF) amplifier, audio amplifier, often need very high voltage to obtain enough output power and voltage amplitude
The simulated 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 output
It clearly shows that the output voltage ripple for an output voltage of 32.18 V in open loop condition is about 1.18 V
Summary
For the function of the power supply using the low voltage battery, analog circuits, such as radio-frequency (RF) amplifier, audio amplifier, often need very high voltage to obtain enough output power and voltage amplitude. This is done by boosting the minimum voltage to the required high voltage. The KY boost converter [8] [9] [10] is presented to overcome this problem These converters [8] [9] [10] do not obtain the expected output voltage and having large amount of output voltage ripple. To reduce the ripple in a very effective manner PSO based controller is used and the detailed illustration of the proposed converter is described along with some experimental results to justify the effectiveness of such a converter
