DC-DC converters are power electronic converters that convert one level of DC voltage to other level using switching action. They are widely used in industrial applications such as DC motor drives, computer systems, adapters, communication equipments. One of the main problems of DC-DC converters is the adequate selection of control scheme because these systems are non-linear and show complex behavior patterns. Crucial to the performance of power converter, is the choice of control methods. A linear PID controller designed for regular operation cannot give satisfactory performance when the operating point changes due to line variation and load variation. Sliding Mode Control has gained importance as a design tool for the robust control of linear and non-linear systems. SMC provides inherent order reduction, robustness against system uncertainties, disturbances, and implicit stability proof. The design allows a high-performance control system at low cost. The application of the Sliding Mode Control techniques to DC-DC converter is analyzed with respect to buck converter using MATLAB/SIMULINKTM based simulation.
