When a switch (20) that is in series with the inductive load (10) is
turned on, the rise behavior of the current (I) is first of all detected
until a nominal value (Iref) is reached, and a pulse duty factor (Te/Ta)
of a pulse width modulator device (30) is determined from said rise
behavior. Immediately after the nominal value (Iref) of the current (I)
has been reached, the switch (20) is driven in a conventional manner by
the pulse width modulator device (30), using the pulse duty factor
(Te/Ta) that has been determined, in order to finely adjust the pulse
duty factor (Te/Ta). The invention largely avoids overshoots during
control and the adjustment time is thus considerably shorter than in
conventional drive circuits.
