Buck-Boost-Based DC–DC Converters, a Comprehensive Review on Topologies, Control Strategies, Performance Evaluations, and Emerging Utilizations in Last Decade

Buck-boost-based DC-DC converters are frequently used in power-electronics-based systems,covering a wide range from low voltages and power levels up to thousands of volts and megawatt-scale powerin industrial applications. With the growing penetration of renewable energy systems featuring wide inputvoltage ranges, battery-supported power units, electric vehicle charging stations, electrified transportationsystems, on-grid and off-grid integrations, industrial applications, and high-performance electronic systems,the use of buck-boost converters has significantly increased. These converters represent an important researchtopic in modern power electronics due to their step-up/step-down performance capability and their structuralflexibility across different power levels. In recent years, in addition to Single-Ended Primary-InductorConverter (SEPIC), Ćuk, Zeta, and classical buck-boost configurations, extensive research has focused onhigh-efficiency switching Technologies. Gallium Nitride (GaN) and Silicon Carbide (SiC) wide-bandgap(WBG) semiconductor-based topologies, interleaved operation techniques, synchronous rectificationarchitectures, isolated and non-isolated configurations, soft-switching methods, and sensorless controlstrategies are samples of these designs. These studies generally concentrate on specific subcategories;however, the overall trends, technological developments, and design variations within the broader topologyfamily need to be addressed in a more holistic manner to enable fair comparison across different applicationsand power levels. Besides the converter topologies themselves, the control of these converters is also animportant topic, and various model-based and model-free based controllers, dual voltage–current controlsystems, and artificial intelligent-based methods have been widely considered. This review study aims toprovide a comprehensive evaluation of current approaches and recent advances in the literature focusing onrenewable energy sources integration by classifying buck-boost converters from topology structures tocontrol methods, considering on developments over the last decade. The advantages and disadvantages ofdifferent topologies and control systems, along with comparative perspectives, are presented.
