Abstract
An electronic switch includes a load path connected in series with the load and a drive terminal for receiving a drive signal. The electronic switch is operable to switch between a first operation state and a second operation state dependent on the drive signal. In a first switching cycle, the electronic switch is switched from the first operation state to the second operation state and a voltage across the load is evaluated during the first switching cycle in order to obtain a measured switching profile. The measured switching profile is compared with a reference profile. A drive profile dependent on the comparison is provided. The drive profile is used to drive the electronic switch in a second switching cycle after the first switching cycle. At least two drive parameters are used at different times in the at least one second switching cycle to drive the electronic switch.
