ELECTRICITY GENERATOR

摘要

The invention relates to an electricity generator comprising: a first converter (20) which can convert a variation in energy to be recovered into a corresponding excess of electric charges; a circuit (30) for collecting the excess electric charge, said circuit being provided with a first controllable mechanical switch (48); and a device (34) for controlling the first switch, which can control the switching of the switch to the closed position when the excess electric charge exceeds a first pre-determined threshold. The switch (48) is a magnetic switch and the control device (34) comprises a variable magnetic field source which controls the switching of the first switch to the closed position only when the excess electric charge exceeds the first pre-determined threshold.
