This research proposes a novel topology, a modified DC-DC Buck-Boost converter, with characteristics of voltage boost and low input current ripple. A comprehensive analysis of the proposed converter cells will be elaborated in this study. Furthermore, a control technique is designed for the proposed converter. A double-loop control method using Proportional-Integral (PI) is employed in this research. The outer loop controls the output voltage, while the inner loop is used to control the inductor current. Simulation and experimental results with various scenarios have been conducted, including input voltage variations and output load variations on the converter, which are then analyzed and presented to validate the proposed concept.
