Zusammenfassung:	A switching system is disclosed having a switching arm with a high-side switch and a low-side switch. A control system switches the switching arm alternately between a first configuration, in which the high-side switch is open and the low-side switch is closed, and a second configuration, in which the high-side switch is closed and the low-side switch is open. The control system commands, for each switching operation, the opening of the switch that is initially closed, and then, at the end of a dead time, commands the closure of the switch that is initially open. The system has device for measuring a switch voltage present between the terminals of one of the switches. For each switching operation, the control system, following the command to open the switch initially closed, monitors the measured switch voltage, and determine the dead time for the switching operation based on the monitored switch voltage.
