Abstract

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.
