Abstract: DC–DC boost converters are widely used in modern power electronic systems to step up low input voltage to a higher regulated output. This paper presents a comparative analysis of Single Input Single Output (SISO) and Multi-Input Single Output (MISO) boost converter topologies. The SISO converter, based on inductor energy storage and controlled switching, is simple, cost-effective, and suitable for low-power applications. this work presents a unified comparative investigation of SISO and MISO boost converters under multiple operating conditions using small-signal state-space modeling and MATLAB/Simulink analysis. The proposed study additionally evaluates the dynamic behavior and stability characteristics of hybrid-source MISO configurations incorporating DC, AC, and fuel-cell inputs, thereby providing practical insight for renewable-energy-based power conversion systems.

Keywords: DC-DC Boost Converter, SISO Converter, MISO Converter, Hybrid Energy System, Small Signal Modeling, Renewable Energy Integration.
