Buck-boost DC/DC converters have beenextensively employed in stepping up/down the voltage forPV applications. The input and the output port current ofthe traditional quadratic buck-boost converter arediscontinuous, which result in increased input and outputcurrent ripples and complicate the design of the input andoutput filters. Hence these problems can be solved by usinga modified quadratic buck boost converter, which provideswider voltage conversion ratio with continuous input andoutput ports current. Dual output can be derived from thissingle input converter for multiple output applications. Alsoa fuzzy logic controller can be designed for this proposedconverter for better and faster performance.
