A method for operating an inverter, an inverter, as well as control unit for operating of the inverter

摘要

The present invention relates to a method for operating an inverter (1), in particular power supply 1, wherein the inverter (1) a plurality of phase systems (2, 3, 4), each with an outer conductor (7, 8, 9) and the operation takes place on the basis of at least one operating parameter. In this case, it is provided that for at least one of the phase systems (2, 3, 4) a phase current gradient of the in the phase system (2, 3, 4) flowing current is determined, in the case of exceeding a threshold value by virtue of the phase current gradient or by means of an this derived quantity of the counter reading of a counter is incremented and the counter reading is used for determining the operating parameter. The present invention also relates to an inverter (1) and a control unit (14) for the operation of the inverter (1).
