Abstract
A device serves to control an electrical load of at least two single loads connected in series. Each of the at least two single loads is connected in parallel to a controllable switch, so that each of the at least two single loads can be switched independently of one another. In addition, a driver stage that drives a current into the electrical load is present. The controllable switches can be controlled by the control unit. A dummy load is connected in series to the at least two single loads.
Claims24
