Abstract In existing DC-DC converters, the step-up/step-down capacity of Buck, Boost, and bidirectional converters is limited, which greatly reduces their application sphere. A step-up-protype switched-capacitor network and a step-down-protype switched-capacitor network are proposed in the paper. Thus, a series of DC-DC converters are put forward based on them: the single-stage step-up converter, the single-stage step-down converter, bidirectional step-up/step-down converter, the multi-input step-up converter and the multi-stage step-down converter. Derivation processes of these five converter topologies are presented and corresponding operating principles of them are analysised in detail. Simulation and researches are provided to verify the correctness of the proposed converters.
