Abstract: This paper proposes the application of super-twisting control for the output voltage regulation of dual input buck boost converter (DIBB). The design method is clearly illustrated for dual input buck boost converter with the above control strategy. The simulation results of DIBB for its responses to load and line regulations are compared with the conventional sliding mode controller. The results reveal the effectiveness of the super- twisting based sliding mode control over conventional sliding mode control. The simulation results also reveal the reduction of settling time and chattering.
