Abstract
A method for identifying a cause for insufficiency of an output voltage reduced to or below an undervoltage set value comprises a first comparison step for comparing the output voltage to a fixed first undervoltage set value and a second comparison step for comparing the output voltage to a second undervoltage set value that follows up the output voltage with a time lag, wherein the cause for the output voltage insufficiency is identified based on the steps and notified as a warning. As a preferable mode, the first undervoltage set value is set by means of a reverse conducting voltage of a voltage regulating diode Dand the second undervoltage set value is set by means of a charging voltage of a capacitor Cfor directly or indirectly charging the output voltage.
