摘要
在现有的DC-DC变换器中,Buck、Boost及双向变换器的升降压能力有限,在一定程度上限制了其适用范围。本文提出一种升压型开关电容网络和一种降压型开关电容网络,并在此基础上推演出一系列DC-DC变换器:单级升压变换器、单级降压变换器、双向升降压变换器、多输入升压变换器和多级降压变换器。给出了这五类变换器拓扑的推演过程,详细分析了其工作原理,并通过仿真研究证明了理论分析的正确性。
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.
