Comparison of Three Buck Topologies for Wide Output Voltage Applications
2023 IEEE Applied Power Electronics Conference and Exposition (APEC), 2023 This paper investigates the suitability of three step-down dc-dc converter topologies as the final conversion stage in a wide output voltage modular ac-dc power supply. Single-phase, two-phase and three-level buck converters are evaluated over a wide range of outputs using analytical models and physical measurements.
