Abstract
A method carries out a self-test of an electrical converter circuit, by use of a control device, proceeding from a known operating point at which a predetermined electrical operating variable has a predetermined starting value, a measurement cycle is begun by the converter circuit being operated. It is additionally provided that the time since the starting of the measurement cycle is detected, and the electrical operating variable and the time constitute two monitoring variables of the self-test. The measurement cycle is ended if one of the two monitoring variables satisfies an ending criterion. A test value is then formed from a measurement value of the other of the two monitoring variables at the end of the measurement cycle and a check is made to ascertain whether the test value lies outside a predetermined reference interval. If so an error signal is generated.
