Voltage regulation of soft switched interleaved boost converter using fuzzy proportional integral controller

Abstract

This paper discusses about a fuzzy PI controlled three-stage soft switched interleaved boost converter with improved switching method. The proposed fuzzy PI controller has been evaluated against with proportional integral controller. The proposed fuzzy PI controlled soft switched interleaved boost converter model has been developed and tested in MATLAB/SIMULINK environment. Performance of the designed controller is tested with different loading constraints and step change in reference voltage conditions. For effective comparisons, four performance parameters are taken for analysis such as integral of time multiplied absolute error, integral of squared error, integral of absolute error, and settling time. From these simulation results, fuzzy PI controlled soft switched interleaved boost controller has better performance than PI controlled soft switched interleaved boost converter. Experimental verification also conducted to check effectiveness of the proposed fuzzy PI controlled soft switched interleaved boost converter.
