Patent number: 11031931Abstract: A protective device for protection of a semiconductor switch against overvoltages during a deactivation process. A compensation signal is provided at an input of a driver stage for a semiconductor switch to be deactivated if the voltage at the output of the semiconductor switch exceeds a specified threshold, and simultaneously a request to open the semiconductor switch is detected at an input of the driver stage for the semiconductor switch. The compensation signal is limited to a specified duration. On the basis of the compensation signal provided in the aforementioned manner, the driver stage for the semiconductor switch partly controls the semiconductor switch in order to prevent an excessively quick opening of the semiconductor switch.Type: GrantFiled: March 9, 2017Date of Patent: June 8, 2021Assignee: ROBERT BOSCH GMBHInventors: Matthias Heil, Peter Sinn, Sebastian Laich, Tobias Richter
