Dalam makalah ini, kami mengkaji penggunaan teknik pengurangan hingar mod biasa untuk peralatan elektronik dalam kenderaan dalam reka bentuk instrumen sebenar. Kami telah menambah baik model litar bunyi mod biasa yang mengalir ke abah-abah wayar untuk menambah kesan kapasitor pintasan yang terletak berhampiran LSI. Kami menganalisis model litar yang dipertingkatkan menggunakan simulator litar dan mengesahkan keberkesanan keadaan pengurangan hingar yang diperoleh daripada model litar. Ia juga telah disahkan bahawa mengimbangi ketidakpadanan impedans dalam bahagian PCB memerlukan pemalar litar yang lebih besar daripada yang diperlukan untuk melakukan ketidakpadanan impedans dalam bahagian LSI. Papan litar penilaian yang terdiri daripada mikrokomputer automotif telah diprototaip untuk mencuba kesan pengurangan hingar mod biasa papan tersebut. Keputusan eksperimen menunjukkan kesan pengurangan hingar papan. Keputusan eksperimen juga mendedahkan bahawa tahap ketidakpadanan impedans dalam bahagian LSI boleh dianggarkan dengan menggunakan PCB yang mempunyai impedans yang diketahui. Kami selanjutnya bertanya tentang pengoptimuman parameter impedans, yang sukar untuk produk sebenar pada masa ini. Untuk memenuhi keadaan pengurangan hingar yang terdiri daripada banyak parameter, kami mencadangkan kaedah reka bentuk menggunakan algoritma pengoptimuman dan simulator medan elektromagnet, dan mengesahkan keberkesanannya.

Abstract: In this paper, we studied the use of common-mode noise reduction technique for in-vehicle electronic equipment in an actual instrument design. We have improved the circuit model of the common-mode noise that flows to the wire harness to add the effect of a bypass capacitor located near the LSI. We analyzed the improved circuit model using a circuit simulator and verified the effectiveness of the noise reduction condition derived from the circuit model. It was also confirmed that offsetting the impedance mismatch in the PCB section requires to make a circuit constant larger than that necessary for doing the impedance mismatch in the LSI section. An evaluation circuit board comprising an automotive microcomputer was prototyped to experiment on the common-mode noise reduction effect of the board. The experimental results showed the noise reduction effect of the board. The experimental results also revealed that the degree of impedance mismatch in the LSI section can be estimated by using a PCB having a known impedance. We further inquired into the optimization of impedance parameters, which is difficult for actual products at present. To satisfy the noise reduction condition composed of numerous parameters, we proposed a design method using an optimization algorithm and an electromagnetic field simulator, and confirmed its effectiveness.
