The invention relates to a method for setting a dead time between the opening of a first switching element () of a half bridge () and the closing of a second switching element () of the half bridge (), comprising the steps: reducing the dead time of a switching cycle relative to the dead time of a preceding switching cycle, and determining a temperature of at least one of the switching elements (); wherein the steps of reducing the dead time and of determining the temperature are repeated for subsequent switching cycles until a critical dead time is reached, in the case of which a termination condition, which depends on the determined temperature, is fulfilled; and wherein the dead time is set using the critical dead time.

In a circuit configuration for generating a stabilized power supply voltage, an in-phase regulator LR and a switched-mode regulator SR are connected in parallel to one another and are between terminal A,where the input voltage is supplied and terminal A,where stabilized output voltage UA is obtained. The regulators are adjusted so that in the normal case, the output voltage of switched-mode regulator SR is slightly higher than that of in-phase regulator LR.
