摘　　要：为了有效抑制共模干扰信号,通过理论分析逆变器中共模干扰形成的原因以及通过逆变器的结构分析逆变器中存在的寄生参数,并且通过电路原理和数学研究共模电压、共模电流与不同寄生参数的关系,得到了对交流测共模电流以及共模电压影响突出的寄生参数,最后通过仿真验证分析结论的正确性,对共模干扰抑制方法具有实际指导和应用价值。To effectively restrain the formation of common mode interference,the causes of common mode interference in inverters are theoretically analyzed,and examines the parasitic parameters existing in inverters through the structure of the inverter.The relationship between common mode voltage,common mode current and different parasitic parameters is studied by circuit principle and mathematical analysis,the parasitic parameters that have the greatest impact on AC measurement of common mode current and common mode voltage are obtained.Finally,the correctness of the analysis conclusion is verified by simulation experiments.It has practical guidance and application value for common mode interference suppression methods.
