Zusammenfassung:	An active voltage snubber includes a ground terminal and an input terminal, and a snubber capacitor. A snubbing-activation device is designed to connect the input terminal to a second terminal of the snubber capacitor with a view to charging the snubber capacitor via this second terminal. Also included is a discharging switch for discharging the snubber capacitor, and a control circuit for controlling the discharging switch, which is designed to close the discharging switch so as to make the snubber capacitor discharge via its second terminal through the discharging switch. The control circuit is powered electrically by the snubber capacitor by being connected to the second terminal of the snubber capacitor so as to receive current from the snubber capacitor.
