A quadratic boost converter (QBC) off ers a wide range of operations and reduced input current ripple that is suitable for hybrid PV/Wind systems. This paper presents a fast response sliding mode controller with more state feedback for the multi-input QBC system connected to DC micro-grid. The control scheme elaborates on the systematic process of arriving controllable canonical form, the advent of the sliding surface, determination of control law, and explanation of sliding mode existence manifold—the controllable canonical form obtained from state-space equations. The proposed controller ensures a model reference robust dynamics against changing operating conditions, variations of circuit parameters, and external disturbances. Obtained sliding surface satisfy Routh–Hurwitz property, and the switching law maintains the converter in sliding mode. The dynamics are studied using MATLAB/Simulink, and the stability of the system is analysed using the bode plot. A prototype is set up for the two-input QBC, and the experimental results are presented to validate the simulation results.
