Study on Conductive Emission Overstandard Based on Lin Bus Low Frequency Current Method
Abstract: In EMC current conduction emission(CCE) test,the PK and QP emission of Lin bus measured at 500 kHz~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.
Keywords: Lin bus;Fourier transform;current probe;EMC
