摘要：The invention relates to a control device for operating a load circuit providedwith an inductive load, comprising a control stage producing a pulse-width modulatedcontrol signal with measuring disconnection intervals provided in between said controlsignal, a power stage feeding the load circuit and comprising an electronic switch

controlled by the pulse-width modulated control signal and a freewheeling elementwhich is connected in parallel to said load circuit. In order to improve upon said device sothat it is possible to determine in a simple manner the amount of current flowing into theload circuit, a current detection unit for determining the amount of current flowing intothe load circuit prior to the measuring disconnection interval detects the duration offreewheeling time and calculates the value of said current therefrom.
