Cet article explique un mécanisme de génération de mode commun sur une carte de circuit imprimé avec un motif de masse étroit. Une ligne de transmission a sa valeur de degré de déséquilibre. À un point de connexion de deux lignes de transmission présentant différents degrés de déséquilibre, une tension de mode commun est générée proportionnellement à la différence et entraîne le courant de mode commun. Les auteurs proposent une méthode pour évaluer la distribution du courant en mode commun et la vérifier par mesure. Bien que le courant de mode commun calculé soit supérieur à celui mesuré de quelques dB, les deux sont proportionnels au degré de déséquilibre. Une technique de réduction des interférences électromagnétiques, appelée « adaptation des déséquilibres », est également proposée.

Abstract: This paper explains a mechanism of common-mode generation on a printed circuit board with a narrow ground pattern. A transmission line has its value of degree of unbalance. At a connection point of two transmission lines having different degrees of unbalance, common mode voltage is generated proportional to the difference, and it drives common mode current. The authors propose a method to evaluate common mode current distribution and verify it by measurement. Although calculated common mode current is larger than measured one by a few dBs, both of them are proportional to the degree of unbalance. An EMI reduction technique, 'unbalance matching,' is also proposed.
