Abstract
Driver circuit in which a capacitor (), in a manner controlled by a switch control device () which is connected downstream of a current measuring device (), is charged to a reference voltage (Ur) by means of a charging current (Ic), and the charged capacitor is discharged in an oscillating manner via an inductor coil (), wherein the discharging operation is terminated when the current (Ia) through the inductor coil has passed through an entire oscillation period or several oscillation periods, wherein a first controllable switch () is connected in series between a first non-reactive resistor () and the first capacitor () in one of two input paths. Furthermore, a second controllable switch () and a fourth controllable switch () are connected into two output paths, and a second non-reactive resistor () is connected between a second connection (X) of the inductor coil () and a connection for a reference potential (Um). The current measuring device () is connected between the fourth controllable switch () and the first capacitor ().
