Abstract:

将Boost变换器与Sepic变换器进行有机结合,提出一类Boost-Sepic(BSIC)集成拓扑结构,该结构既扩展了电压增益,又降低了开关管的电压应力,同时保留了两种基本变换器输入电流连续的特点。该文首先把Boost环节与Sepic环节在输入端共用一个输入电感和一个开关,然后将Boost环节与Sepic环节的输出端进行串联,构成基本集成变换器拓扑(BSIC)。在此基础上,将耦合电感的匝比引入到集成变换器电压增益的函数中,进一步提高了变换器的电压增益,减小了开关管电压应力,有利于优化整体效率。给出了集成变换器的推演步骤,详细分析了基于耦合电感的CI-BSIC集成变换器的工作原理,讨论了电路参数对其稳态性能的影响。最后,通过一台数字式实验样机验证了理论分析的正确性和有效性。
