jcir.5.4.13943 Reaching Condition Techniques For Mitigation Of Chattering In Sliding Mode Controlled Buck Converter K.B. Siddesh Basavaraja BANAKARA Journal on Circuits And Systems 2322–035X 5 4 33 38 10.26634/jcir.5.4.13943 Buck Converter, Chattering, Sliding Mode Control, Lyapunov Function Approach, The Direct Switching Function, Reaching Laws This paper presents a reaching condition methods for Sliding Mode Controlled DC-DC Buck Converter. Three approaches are specified for reaching conditions. The approaches comparing among the chattering, which is effectively reduced the chattering and fast speed is kept. The approaches are direct switching, lyapunov and reaching law approach. Among them reaching law approach minimizes the chattering and effective output is obtained. Various output voltages are obtained by keeping V as constant and chattering is analysed, minimized and also takes very less ref time to reach the steady state. A simulation results shows better reduction of chattering by the reaching law. September - November 2017 Copyright © 2017 i-manager publications.
