  • Method for switching over a semiconductor switch
    Patent number: 10911043
    Abstract: A device and a method for switching over a semiconductor switch with a switching signal acting on a control connection of the semiconductor switch, the switching signal being switched over as a response to registering a switchover of an activation signal; a down time being ascertained between the start of the switchover of the switching signal and the switchover of the semiconductor switch; the switchover of the semiconductor switch being delayed by a waiting period, for example by delaying the output of the switching signal and/or changing the signal level, so that an actual switching time, corresponding to a setpoint switching time, between the registration of the switchover of the activation signal and the switchover of the semiconductor switch is obtained.
