Abstract

A system and a method for identifying a non-switching semiconductor switch are proposed. The system has a first acquisition component, a second acquisition component and a determination unit. The first acquisition component is designed to acquire a profile of an electrical variable of a first semiconductor switch driven by way of a first drive signal. The second acquisition component is designed to acquire a profile of an electrical variable of a second semiconductor switch driven by way of a second drive signal and connected in parallel with the first semiconductor switch. The determination unit is designed to use the profile of the electrical variable of the first semiconductor switch and the profile of the electrical variable of the second semiconductor switch as a basis for determining an output signal that allows identification of a non-switching semiconductor switch for the first semiconductor switch and/or the second semiconductor switch.
