摘要:
对大功率变电柜所产生的传导电磁干扰问题进行分析,首先建立了传导噪声高频电路的等效模型,阐述噪声电流与电压的计算方法,对共模和差模传导噪声进行分析并建模,作为后续的传导噪声提取和分离的理论依据. 提出散射参数法提取噪声源阻抗,并对传导噪声抑制方法进行研究,设计了针对本电路的EMI滤波器,通过实验进行抑制效果的验证,为实际的工程整改提供了理论依据.
Abstract:
This paper analyzes the problem of conducted electromagnetic interference generated by high-power substations. First,an equivalent model of high-frequency circuits for conducted noise is established. The calculation method of noise current and voltage is explained. Common-mode and differential-mode conducted noise are analyzed and modelled. The model is established to provide the theoretical basis for the subsequent extraction and separation of conducted noise. A scattering parameter method is proposed to extract the noise source impedance,and the conducted noise suppression method is studied. An EMI filter for this circuit is designed,and the suppression effect is experimentally tested. The verification provides a theoretical basis for the actual engineering rectification.
