Abstract
The invention relates to a control device for triggering a semi-conductor switch of an inverter, the control device comprising: a switching signal amplification device, which is designed to amplify a switching signal generated by a control regulation of the inverter, and to generate a first switching control signal that triggers the semi-conductor switch in a switching mode; a current regulation device, which is coupled to a current sensor output of the semiconductor switch and is designed to generate a second switching control signal that triggers the semi-conductor switch in a linear mode; and a selection device, which is coupled to the switching signal amplification device and the current regulation device and is designed to output, on the basis of at least one mode selection signal, either the first switching control signal or the second switching control signal in order to trigger a control terminal of the semi-conductor switch.
