摘　　要：EMC电流法传导发射(CCE)测试中,在500kHz~2MHz频道测量LIN总线的PK和QP发射量超标。本文对上海必维实验室中得到的数据进行分析,使用MATLAB的Simulink仿真工具建立电路图仿真模拟LIN总线上电流变化量,并将电流变化量傅里叶变换,得出结果与实验结果一致。In EMC current conduction emission(CCE)test,the PK and QP emission of Lin bus measured at500 k Hz~2 MHz channel exceeded the standard.In this paper,the data obtained from Shanghai Biwei Laboratory are analyzed,and the circuit diagram is built using Simulink simulation tool of MATLAB to simulate the current change on Lin bus.The result is in agreement with the experimental result.
