Abstract
A method for control and discharge control of an electrical load, in which the control and discharge occurs by means of a control frame and a discharge frame, and in which one control frame and one discharge frame represent one switching cycle for the electrical load. A plurality of switching cycles are arranged following one another, wherein a controllable switch is connected in parallel to each point load so that each point load can be switched independently of the other point load during the switching cycle. A control unit monitors the electrical current flowing in the electrical load, and the control unit uses an actual/setpoint comparison to control the current to an adjustable setpoint so that a current that is as constant as possible flows into the electrical load. The controllable switches switch on the point loads during the control frame of a switching cycle, and the controllable switches switch off the point loads during the discharge frame of a switching cycle.
