| Abstract(in English) | Power line communication (PLC) is a system using a main-line network without newly constructing any transmission line system. For the signal transmission, a two-conductor line system is fundamental and the electromagnetic fields are opened so that an EMI (electromagnetic interference) problem would become serious. Generally, a transmission-line network theory is based on telegrapher's equations, a mode-decomposition technique is applied to solve the equations. A typical set of orthogonal modes for the two-conductor line is differential and common modes, and the common-mode current mainly causes a radiated emission. When a PLC modem of a differential-mode source is connected to an asymmetric load circuit, the common mode component would generate there. Thus the estimation of the common-mode current becomes important. In this article, consideration ways for equivalent circuit expressions for discussing the common-mode current in power-line networks are discussed and several expressions are proposed. |
