Abstract
The invention relates to a system (30) and a method for identifying a non-switching semiconductor switch (34a, 36a). The system (30) comprises a first semiconductor switch (34a), a first semiconductor component (34b), a second semiconductor switch (36a), a second semiconductor component (36b), a first resistor (64b), a second resistor (66b) and a detection unit (38). The detection unit (38) is designed to identify, on the basis of a curve of a first voltage dropping across the first resistor (64b), whether the first semiconductor switch (34a) is not switching. The detection unit (38) is designed to identify, on the basis of a curve of a second voltage dropping across the second resistor (66b), whether the second semiconductor switch (36a) is not switching.
