Abstract
A gate signal is generated by summation of multiple signal profiles. The gate signal is applied to a switching device to switch the switching device between an off state and an on state. While the gate signal is applied to the switching device, at least an n-th order derivative of a load signal of the switching device is detected, with n being an integer which is equal to or larger than 2. Depending on the detected n-th order derivative, one or more of the signal profiles are adapted.
