Abstract
Official abstract text for this publication.
The invention relates to a method for operating an inverter ( 1 ), in particular a pulse-controlled inverter, comprising multiple phase systems ( 2, 3, 4 ), each of which has an outer conductor ( 7, 8, 9 ) and at least one semiconductor component ( 12, 13 ), and a temperature monitoring device ( 15 ) that has multiple temperature sensors ( 16, 17, 18 ) which sense the temperature of at least one part of at least one of the phase systems ( 2, 3, 4 ). In said method, a temperature gradient is determined from each of the sensed temperatures, the difference of the determined temperature gradients from each other is ascertained, and if the difference exceeds at least one threshold value, a fault of a cooling device of the inverter ( 1 ) is identified. The invention further relates to an inverter ( 1 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating an inverter, wherein the inverter has a plurality of phase systems, each with an outer conductor and at least one semiconductor component, and also a temperature monitoring device that has a plurality of temperature sensors, wherein the temperature sensors are used to sense the temperature of at least one portion of at least one of the phase systems, the method comprising: ascertaining a temperature gradient from each of the sens…
