METHOD FOR REDUCING COMMON MODE CURRENT

摘要

A method for reducing the common mode current (i) circulating between the internal ground (13) of an electrical circuit (4) and the earth when electrical energy is exchanged between an electrical energy storage unit of the electrical circuit (4) and an electrical energy source external to said circuit (4), in which method an electronic component (21) is used to apply an electrical quantity (Vs, Is) at a point (26) connected via at least one impedance (28) to an electrical line (5) of said circuit (4) via which electrical energy is exchanged, said electrical quantity (Vs, Is) applied making it possible to reduce the common mode current (i).

1. A method for reducing the common mode current circulating between the internal ground of an electrical circuit and the earth, when electrical energy is exchanged between an electrical energy storage unit of the electrical circuit and an electrical energy source external to said circuit, the method comprising:
applying, by an electronic component, an electrical quantity at an injection point connected via at least one impedance to an electrical line of said circuit via which said electrical energy is exchanged, said electrical quantity applied thereby making it possible to reduce the common mode current circulating between the internal ground of the circuit and the earth, wherein said electrical quantity is applied by the electronic component at least as a function of a signal representative of the common mode current measured on the electrical line between the electrical energy source of the network and the impedance or impedances connecting the electrical line to said injection point.
