Title: The Innovations of Alain Carnel
Introduction
Alain Carnel is a notable inventor based in Poitiers, France. He has made significant contributions to the field of electrical engineering, particularly in the development of devices for measuring electrical parameters. With a total of 4 patents to his name, Carnel's work reflects a deep understanding of electrical systems and their applications.
Latest Patents
One of Carnel's latest patents is an electrical device for measuring electrical parameters. This innovative device utilizes a shunt and an electronic measuring circuit that floats at the potential of the shunt. It features a first voltage divider connected between the shunt and a neutral point, providing a first voltage signal to the circuit. To enhance the decoupling of potential between the shunt and the intermediate point of the first voltage divider, the device includes an additional terminal connected to the shunt via a second voltage divider. The intermediate point of this second divider supplies a second voltage signal, which is used differentially with the first.
Another significant invention by Carnel is an input circuit for an electrical energy meter. This circuit comprises a current path and a voltage path, with the current path associated with a mutual conductance transformer. To compensate for the differentiating function of the transformer without introducing interference signals, the current path includes an active filter connected as an integrator. This filter is equipped with a coupling capacitance suitable for blocking low-frequency signals.
