(JA) 通信システム
Abstract: front page image
(EN)Provided is a communications system that performs communications while retaining high voltage insulation, therefore enabling communications to be performed by connecting a control circuit operating at a low voltage and a non-control circuit operating at a high voltage via a propagation layer having a waveguide structure. Specifically, a displacement current (surge current) flows between a high voltage circuit and a low voltage circuit, caused by potential difference generated in the high voltage circuit. A surge current protection circuit is provided, preventing input beyond a rating being applied to a communications module and the low voltage circuit by such surge currents.
(FR)Cette invention concerne un système de transmission qui assure la transmission tout en maintenant une isolation haute tension et permet ainsi de réaliser la transmission par connexion d'un circuit de commande fonctionnant sous faible tension et d'un circuit de non commande fonctionnant sous haute tension par l'intermédiaire d'une couche de propagation présentant une structure de guide d'ondes. Plus spécifiquement, un courant de déplacement (courant de surtension) circule entre un circuit haute tension et un circuit basse tension, induit par une différence de potentiel générée dans le circuit haute tension. Un circuit de protection contre les surtensions est mis en œuvre pour empêcher l'entrée desdits courants de surtension au-delà d'une valeur nominale s'appliquant à un module de transmission et au circuit basse tension.
(JA) 高耐圧絶縁を維持しつつ通信を行う通信システムを提供するため、低電圧動作する制御回路と高電圧動作する非制御回路とを導波路構造を持つ伝搬層を介して接続し、通信を行うようにする。特に、高電圧回路で生じた電位変動に起因して、高電圧回路と低電圧回路の間に変位電流(サージ電流)が流れる。サージ電流保護回路を設け、通信モジュール及び低電圧回路にこのようなサージ電流による定格外の入力が印加されるのを防止する。
