Title (EN) CURRENT SENSOR
(FR) CAPTEUR DE COURANT
Abstract: front page image
(EN)An apparatus and method make use of a single shunt and two or more instrumentation amplifiers, switchably measuring voltages at the shunt. This permits current measurement. At times each instrumentation amplifier has its input shorted, which permits zeroing out many sources of offset in the signal path of that amplifier. Dynamic range is several orders of magnitude better than known current measurement approaches, permitting coulometry.
(FR)La présente invention concerne un appareil et un procédé faisant usage d'un seul shunt et de deux amplificateurs d'instrumentation ou plus, mesurant, de manière commutable, des tensions au niveau du shunt. Ceci permet d'effectuer des mesures de courant. Chaque amplificateur d'instrumentation voit son entrée court-circuitée à des instants donnés, ce qui permet de mettre à zéro de nombreuses sources de décalage dans le chemin de signal de cet amplificateur. Le domaine dynamique est meilleur, de plusieurs ordres de grandeur, que les approches de mesures de courant connues, permettant la coulométrie.
