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.
Claims23
Device for controlling an electrical load comprising:
- at least two single loads, wherein the at least two single loads are connected in series and 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 is configured to be switched independently of one another,
- a driver stage, which drives a current into the electrical load, and
- a control unit, which controls the controllable switches,
- wherein at least one dummy load is connected in series to the at least two single loads and is configured to be switched when one of the at least two single loads is switched to prevent load surges.
