Abstract
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.
