Abstract
A new Quadratic Bi-Directional Buck-Boost Converter(QBC) is simulated and its performance is validated in this paper. The aim of this paper is to provide a new configuration of a non-isolated Buck-Boost converter with an additional inductor and capacitor and switches. Broad span of the output voltage is one of the advantages i.e., an ultra-high step-up or step-down voltage conversion ratio can be achieved using four power switches in two parallel legs. The proposed topology of QBC includes continuous low ripple input current and positive output voltage. The continuity of the input current makes this type of converters more convenient for renewable energy sources like Solar PV and also decreases the current stress on the load terminal capacitor. Simulations have been carried out in continuous current mode (CCM). Eventually, the implementation of the proposed converter topology is validated based on the simulation outcomes from MATLAB Simulink model.
