Sliding mode controller for dual input buck boost converter

This paper presents the design procedure of the sliding mode controller in cascaded structure for the output voltage regulation of dual input buck boost converter (DIBB) in continuous conduction mode. 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 reveal the effectiveness of the cascaded sliding mode controller. The simulation results also reveal the reduction of initial transients like overshoot and settling time.
