Closed loop control of dual buck-boost AC/DC converter for DC nano-grid using fuzzy-logic-controller

Abstract

DC-grid has become more popular and became an efficient alternative for DC-grids.AC output of wind generator is applied to a dual buck boost converter. The DBBC is filtered using CLL filter. Our work mainly focus onnano-grid system with PRC and Fuzzy Logic controllers. The performance of NGS with PRC and FLC are compared and their results are presented. The results indicate that FLC controlled DBBC gives superior response.
