  • Patent number: 11664739
    Abstract: In brief, the invention relates in particular to a converter (100) comprising a plurality of rectifier arms (110), making it possible in particular to rectify AC electrical signals available on the electrical phases (U, V, W) of an electrical grid. To balance the electrical signals coming from the electrical phases (U, V, W) of the electrical grid, and to limit a modulation amplitude of the DC signal generated by the converter (100) between its output terminals (S1, S2), the converter (100) also comprises a correction arm (120) that determines an amplitude of electric current flowing in a neutral (N) of the electrical grid and that generates an opposing electric current of equal or if not close amplitude. The invention also relates to a two-way charger (10) comprising such a converter (100) and one or more active double bridges (200), such that an output (S3, S4) of the active double bridges (200) is electrically isolated from the converter (100).

  • Patent number: 8109076
    Abstract: A method and a device for purging an injector in a fuel injector system of use in regeneration of a particle filter. The aging of fuel is determined and compared with a fuel aging threshold value, and a purge request is activated if the threshold value is exceeded. On activating the purge request the satisfaction of the conditions of purge activation are verified and, if satisfied, the purge is activated. The purge is continued while the conditions are satisfied until the quantity of fuel purged reaches a quantity of fuel to be purged.

  • Patent number: 7707984
    Abstract: The invention relates to a method for controlling a low-voltage-powered plug (2) for preheating a diesel engine (1) air/fuel mixture. The plug (2) is powered by pulses having a predetermined amplitude and duration, said amplitude being less than a maximum amplitude (PWM_MAX). The amplitude and duration of the voltage pulses powering the plug (2) are controlled as a function of first parameters including the duration of the preceding pulses and the duration between successive preceding pulses.
