Abstract (en)
[origin: EP2546499A1] An electrical drive arrangement for at least one fuel injector (54) of a fuel injection system comprises: a buffer capacitor (60) adapted to store energy; a charging stage (64) for charging said buffer capacitor (60) to a target charge voltage (V charge ); and an injector driver stage (52) operatively connected to a fuel injector (54). A voltage regulation device (62) is operatively connected between the buffer capacitor (60) and the injector driver stage (52) and configured to supply an operating voltage to the driver stage. A controller (82) is configured to determine said target charge voltage (V charge ) for the buffer capacitor (60) depending on pre-set conditions, while the charging stage (64) is adapted to receive from the controller an input representative of the target charge voltage.
