Abstract:
The invention describes a method for pulse-width modulated (PWM) current control of a load current (IL) of an inductive load (L) by means of at least one switch element (T 1 ) for switching the load current (IL), wherein a first operating mode (I) is executed for operating the inductive load (L) if a change in the current setpoint value (ISOLL) occurs, wherein an initial duty-cycle (DC) of the pulse-width modulation (PWM) is determined in the first operating mode (I), which is used for operating the inductive load (L) in a second operating mode (II), and a switching state of the switch element (T 1 ) is established in the first operating mode (I) depending on whether a current setpoint value (ISOLL) of the load current (IL) is higher or lower than a current setpoint value (ISOLL,t−1) of a directly preceding cycle, wherein the switching state is maintained until achieving a current limit value (ISOLL,o,I, ISOLL,u,I) and is switched over upon achieving the current limit value (ISOLL,o,I, ISOLL,u,I), wherein multiple switch-overs of the switching state of the switch element (T 1 ) occur in order to generate a predetermined number (N) of periods, and on the basis of at least one part of the predetermined number (N) of periods, the duty-cycle (DC, DCmean) of the pulse-width modulation (PWM) is determined, which is used as the initial duty cycle (DC) for the second operating mode (II). The invention further describes a corresponding electronic circuit arrangement.

Claim (Index 2):
The method as claimed in  claim 1 , wherein an average duty cycle is determined based on at least the portion of the prescribed number of periods, said average duty cycle being used as the initial duty cycle for the second operating mode.
