摘　　要：变流器中存在有高压和低压电路,其中高压电路在运行过程中产生强电磁干扰,不可避免地耦合到低压电路中。为此,文章研究了变流器中的高低压耦合机理,理论分析了高压电路直流部分、交流部分对低压电路的耦合特征,并通过建立高低压耦合仿真模型,验证了干扰耦合路径及理论分析的正确性,为变流器高低压耦合设计、系统阻抗设计提供依据。There are high-voltage and low-voltage circuits in the converter.The high-voltage circuit generates strong electromagnetic interference during operation and is inevitably coupled to the low-voltage circuit.Therefore,this paper studies the high and low voltage coupling mechanism in the converter,and theoretically analyzes the coupling characteristics of the DC part and the AC part of high-voltage circuit to the low-voltage circuit.By establishing the high and low voltage coupling simulation model,the correctness of the interference coupling path and the theoretical analysis is verified,which provides a basis for the high and low voltage coupling design and system impedance design of converter.
