Abstract: A method for driving a non-linear load element. On account of the non-linear interrelationship between the voltage and the current at the load element and the related non-linear dependence of the power loss on the quantities “voltage” and “current”, an adjustment of the switching speed only on the basis of the power loss in the switching element cannot be carried out with non-linear load elements without being confronted with undesirable switching losses and related electromagnetic noise fields. Therefore, the load current currently flowing in the load element is picked up in addition to the currently determined power loss in the switching element, and the switching speed of the switching element is controlled in dependence on the determined power loss and on the current picked up. The switching speed can be optimally adjusted when driving the non-linear load elements by means of PWM.

Abstract: Disclosed is for controlling a light source by pulse width modulation of a supply voltage. The supply voltage, or a parameter dependent thereon, is measured and the pulse width is controlled as function of the measured value. The supply voltage or parameter is measured at least twice during the pulse and may be cyclically measured. The pulse width of the current or a subsequent pulse is matched to the recorded value of the supply voltage or the parameter. A total value is generated from all of the measured values and compared with a given value and the pulse width of subsequent pulses are matched as function of the difference between the total value and the given value.

Switch loads and high frequency interferences in the supply lines and the corresponding emissions can thus be reduced. The invention also discloses a circuit arrangement in which a corresponding phase staggered control is achieved with only one counter.
