Buck-Boost Converter Topologies for PV Applications: A Comparative Analysis of Design Trade-Offs and Performance Metrics

In this study, a comparative analysis is carried out on two advanced DC-DC power converters with the objective of attaining a significant increase in voltage output. Due to the versatility in stepping up or down the input voltage, buck-boost converters are frequently used in power electronics, renewable energy systems, battery charging, and electric vehicle applications. This analysis focuses on two different quadratic buck boost converter topologies: inverting and non inverting buck-boost converter and compares the it based on important factors including voltage gain, component count, and voltage stress across switches, and output voltage polarity. The results of this study will give important information about the advantages and disadvantages of quadratic buck-boost converters, enabling them to choose and use these converters wisely in real-world applications.
