Abstract: A current conversion method for an electrical device. The electrical device includes a three-phase electric motor and two three-phase inverters. Each inverter is controlled by modulation of at least six non-zero space vectors or space vector modulation. The output voltage of each inverter is given by a reference space vector. For each inverter, the method includes modulating the space vectors by a space-vectors activation sequence having at least two switching intervals in which three adjacent space vectors are used. A device to convert current and a vehicle implementing the current conversion method are provided.

Abstract: The disclosed embodiment relates to a method of controlling a system including at least one inverter with six switches, which is linked to a battery, and supervised by a processor. The method implements a vector modulation, so that it is able to prevent the current linking the battery from passing through zero amperes by means of appropriate control logic. The disclosed embodiment also relates to a device for controlling an electronic component.

Abstract: A power-conversion method for a vehicle including a three-phase electric motor, two three-phase inverters, each inverter being controlled via modulation of at least six spatial vectors, the output voltage of each inverter being given by a spatial vector referred to as “reference spatial vector”. The method includes the following steps: applying an activation sequence to the spatial vectors of one inverter, applying an activation sequence to the spatial vectors of the other inverter, subtracting the reference spatial vector of one inverter from the reference spatial vector of the other inverter and supplying the electric motor with electric power, the voltage inducing the electric power being relative to the vector resulting from the subtraction.

Abstract: A method and device for the non-intrusive determination of the electrical power consumed by a subscriber installation. From the sampled values of the supply current and supply voltage that are delivered to the installation, constituting a consumption signal, the sampled values are grouped in successive observation time windows; the poles and residues of the consumption signal are discriminated in each current window using the pencil method, the set of poles and residues associated with at least one singular value representing a combination of signatures of separate electrical loads; at least the active power consumed by a subset of electrical loads in operation is calculated, over at least the duration of the current observation window, the sum of the active powers consumed by each electrical load satisfying a consumed power function linking these poles and residues.
