Abstract: A method of managing electric energy consumption and/or production dynamics, includes the steps of: sampling an electric energy flow, adapted to be measured by an electricity metering device (1) within a network (15) of an electrical company; calculating a variation ?Ei=(Ei?Ei?1)/?t at regular intervals, where Ei and Ei?1 are two integral sum values of electric energy amounts consolidated over a given number of cycles and ?t represents a time interval between the respective times at which the two values are obtained; adding the variation (?Ei) to analogous variations calculated at previous times, to obtain a cumulative sum of such variations; determining whether the variation and/or the cumulative sum exceed a predetermined threshold value (?DE); transmitting a message over the network (15) from the electricity metering device (1) if the variation and/or cumulative sum exceed the predetermined threshold value (?DE).

Abstract: A conditioning circuit for the transfer of electric charge, which includes a converter module including an energy-storage element applied to which is an input voltage (Vi) and a respective field-effect-transistor switch controlled by a respective driving signal (Vpa, Vpb) for selectively enabling transfer of charge from the energy-storage element to an energy-storage circuit. The field-effect-transistor switch includes a corresponding field-effect transistor and a biasing circuit for biasing a substrate of the transistor, the biasing circuit being connected between the substrate and a reference node at a potential suitable for enabling operation of the transistor in the linear region or in the region of saturation, the biasing circuit being configured for providing a limiting resistance in regard to the current that flows from the reference node in the transistor when it operates in the inhibition region.
