Sliding mode control of two-level Boost DC-DC converter

This paper deals with design of a robust control for two level Boost DC-DC converter (TLBC) operating in continuous conduction mode (CCM). The switched model describing the converter operation is presented and the design procedure of sliding mode control taked as of robust law is described. For validation, Matlab/Simulink software has been used. The robustness of the controller is tested for input voltage variations and load changes. The simulation results show that the efficiency and robustness of this controller are better than those of the cascade PI controller.
