Zusammenfassung:	A method for testing a high-power semiconductor element (11) of power converters of the high-voltage direct current transmission by means of a test circuit (20) comprising a number of voltage-regulated power converter modules (16) switched in series which can be connected to the primary side of a high-current transformer (9) and in which the secondary side of the high-current transformer (9) can be connected to the high-power semiconductor element (1), should enable a high-current test of a high-power semiconductor element by means of a described test circuit at a particularly high service life of the components used. For this purpose, the voltage-regulated power converter modules (16) are switched in a temporal phase of a test cycle into an undefined state.
