Method for driving non-linear load elements based on load current

Device for driving a non-linear load element, including:

• control logic that measures an output voltage Ua at the non-linear load element, and a load current Ia currently flowing through the non-linear load element, and controls an instantaneous switching speed in dependence on the load current (Ia) and an instantaneous power loss (Pv),
• wherein a) a lower voltage threshold Uau is determined when the load current Ia flowing through the non-linear load element exceeds a predefined current value and b) an upper voltage threshold Uao is determined when the load current Ia flowing through the non-linear load element reaches a maximum current value, and
• wherein the instantaneous switching speed is controlled when the output voltage is between the lower voltage threshold Uau and the upper voltage threshold Uao such that the switching speed is set:
• a) at a first speed when an instantaneous power loss is greater than a threshold, and b) at a second speed that is lower than the first speed when the instantaneous power loss is less than or equal to the threshold.
