摘要: 在谐振开关电容变换器中己存在潜电路现象的基础上,系统地提出潜电路路径的图论分析方法,并从能量平衡的角度出友,得到潜电路的发生规律.由此总结出电力电子开关变换器潜电路的一般化分析方法,从而在开发与设计过程中开展安全诊断,及时发现潜电路,必要时加以消除或利用.实验结果证明了该分析方法的正确性.
关键词: 开关变换器, 潜电路分析, 图论, 开关电容, 谐振
Abstract:
Based on the fact that the sneak circuit phenomena are found in resonant switched capacitor (RSC) converters, this paper proposes a graphic method to analyze the sneak circuit , obtains the generation laws of sneak circuit according to the energy equilibrium , and then summarizes a general analysis method for sneak circuits in switch-mode power converters. The proposed method , whose correctness is finally verified by experiments , can be used for the safety diagnosis in design process , and for discovering , eliminating or utilizing sneak circuit paths.
Key words: switch-mode converter, sneak circuit analysis, graphic theory switched capacitor, resonance
