摘要
在谐振开关电容变换器中已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发,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.
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.
