ABSTRACT:
A method for controlling and/or regulating a d.c. converter for at least two electromagnetic valves of an internal combustion engine of a motor vehicle is provided. A current generated by the d.c. converter is supplied to each valve. A determination is made as to when the total currents supplied to the valves constitute a high load for the d.c. converter. If this is the case, the d.c. converter is influenced in the sense of better processing of the high load.
