摘要:
由于二极管整流存在输入电流不平衡放大效应,使得滤波器设计困难。为了更加准确地指导滤波器参数优化设计,文章给出一种数学分析方法来呈现这种电流不平衡放大效应,其建立在开关函数以及等效模型的基础上,运用对称分量法进行推导。在忽略网侧换相重叠的情况下,通过建立电流不平衡度与电压不平衡度之间的数学关系,揭示了LC滤波器谐振频率大小直接影响该放大效应的现象。Matlab/Simulink仿真结果验证了文中结论和分析方法的正确性和有效性。
Abstract:
It is hard to design the filter of diode rectifier due to the input current amplification effect. In order to offer more precise guidance to filter parameter design, this paper brings about this amplification phenomenon by an analysis method which is based on switch function and equivalent model appling symmetrical component to deduce. Without considering the overlap,the relationship between current unbalance and voltage unbalance is derived, which reveal that the resonance frequency of the LC filter directly affects the amplification effect.The correctness and effectiveness of the conclusions and analysis methods are verified by Matlab/Simulink simulation.
