Beschreibung
Zusammenfassung:	A power conversion unit includes a power converter and a controller coupled to the secondary or output stage of the power converter. The power conversion unit is configured to generate an output test voltage or current during a pre-start test period of the power converter, where the output test voltage or current is monitored to determine a converter fault condition. A method of operating a power conversion unit is also included.
