Implentating Fuzzy Logic Controller for Non-Isolated DC-DC Converter
Abstract
The world’s demand for renewable energy sources are growing rapidly, but due to their low voltage generation and high input current requirement they demand a high efficiency, high step-up dc-dc converters .
Practically, the conventional boost converter cannot provide a voltage gain greater than six times of it’s applied voltage due to its parasitic Components associated with passive elements and semiconductor devices. In this project we proposed a high voltage gain dc-dc converter with improved efficiency with fewer components. In this, efficient power conversion is achieved with reduced voltage stress across semiconductor devices. The proposed converter is analyzed, simulated using mat lab/Simulink 2018a.Further; a generalized comparison is done between open loop, PIPWM & fuzzy logic controller. The results obtained by fuzzy logic controller are qualitatively good among the other controller's.
