Beschreibung
Zusammenfassung:	A voltage converter includes a voltage conversion circuit having an inverter including at least one switching arm having a high-side switch and a low-side switch, a resonant tank, a rectifier and an output capacitor. A device for controlling the switches is designed to alternate a phase in which the control device opens the first of the switches and closes a second, and a phase in which the control device opens the second of the switches and closes the first, the control device being designed to provide a dead time between two consecutive phases. The voltage converter further includes a device for measuring an electrical signal of the voltage conversion circuit and the control device is designed to determine, from the measured electrical signal, a crossing instant of the resonance current and the auxiliary current and to calculate a duration of the dead time from the crossing instant.
