Abstract: DC DC converters are used in enormous portable electronic devices in recent days and have experienced tremendous advancement The efficiency of these devices depends on the ability to produce minimized output ripple voltage and their ability to adapt to line load and component variations The effectiveness of the DC DC converters can generally newlineenhanced by means of improvement in the topology of the converter or by providing intelligent closed loop controllers like Fuzzy Logic Controllers FLC NeuralController NC and so on In this research, the latest KY converter topologies namely KY BBC type1 YBBC type 2 and KY BBC SB are taken for consideration. It has a great advantage over the existing topology of luo converter in terms of the reduced ripple voltage and easy implementation compared to the existing luo converter which has the dis advantage of right half plane zero The main objective of this work is to design and implement intelligent closed loop controllers for the existing KY buck boost converter newlinetopology and KY synchronous buck boost converter topology It is observed newlinethat the developed controllers have improved the performance of the KY newlineconverter in terms of reduced ripple voltage less affected by the line variations load variations and circuit component variations It is observed that the proposed controller enhances the performance of the converter suitable for use in low power applications like mp3 players Bluetooth devices LED TV and many more newline newline
