Neste artigo, estudamos o uso da técnica de redução de ruído de modo comum para equipamentos eletrônicos de veículos em um projeto de instrumento real. Melhoramos o modelo de circuito do ruído de modo comum que flui para o chicote de fios para adicionar o efeito de um capacitor de bypass localizado próximo ao LSI. Analisamos o modelo de circuito melhorado usando um simulador de circuito e verificamos a eficácia da condição de redução de ruído derivada do modelo de circuito. Também foi confirmado que compensar a incompatibilidade de impedância na seção da PCB requer tornar uma constante de circuito maior do que a necessária para fazer a incompatibilidade de impedância na seção LSI. Uma placa de circuito de avaliação compreendendo um microcomputador automotivo foi prototipada para experimentar o efeito de redução de ruído de modo comum da placa. Os resultados experimentais mostraram o efeito de redução de ruído da placa. Os resultados experimentais também revelaram que o grau de incompatibilidade de impedância na seção LSI pode ser estimado usando uma PCB com impedância conhecida. Investigamos ainda a otimização dos parâmetros de impedância, o que atualmente é difícil para produtos reais. Para satisfazer a condição de redução de ruído composta por inúmeros parâmetros, propusemos um método de projeto utilizando um algoritmo de otimização e um simulador de campo eletromagnético, e confirmamos sua eficácia.

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.
