Abstract

For current control of an inductive load (4), preferably an electromagnetic pressure regulator, a process is proposed in which an actual current value is detected synchronously and with a delay in relation to the output signal of a current regulator (2). Hereby is prevented the detection of transients superimposed on the actual current value.
