This chapter begins by discussing the necessity of hybrid converters in modern power conversion systems. It then examines three fundamental hybrid converter topologies: the double-step-down (DSD) converter, the dual-path converter, and the three-level converter, focusing on the integration of the 2:1 pre-stage switched-capacitor (SC) with cascading buck cell(s). This chapter details the evolution of these converters from their transformer models to actual circuit implementations, providing comprehensive insights into their operating principles and performances. A comparative analysis highlights the unique advantages and limitations of each topology. The insights gained from these designs enhance understanding of hybrid DC–DC converters and their potential to improve efficiency and adaptability in power conversion applications.
