Abstract
A method of reducing common mode current that flows between an internal ground of an electrical circuit and an Earth ground, the electrical circuit is supplied by an electrical network delivering an alternating voltage. The method includes applying a voltage by the electrical network between the internal ground of the circuit and the Earth ground and applying an additional voltage between the internal ground of the circuit and the Earth ground using an electronic component interposed between the internal ground of the circuit and Earth ground, this additional voltage opposing the voltage applied by the electrical network between the internal ground and the Earth ground so as to reduce the common mode current at the frequency of the electrical network.
