Circuit for detecting and memorising defects in power supply systems

Abstract

Abstract A circuit arrangement detects and stores power line faults. The occurrence of sporadic faults as represented, for example, by inadmissibly long network collapses, which could lead to shut-down of a current supply and, therefore, to downtime of a computer are generally difficult to detect because the faults disappear given a return of the network, as does, therefore, the prerequisite for detecting the cause of such faults. For the purpose of detecting the cause of the fault, the rectified power line voltage is supplied to a comparison circuit followed by a signal circuit. The signal circuit is connected to a memory which influences a display. As a result, power line faults remain stored despite the return of the power line input voltage. The circuit arrangement is particularly suitable for use in power supply systems for data processing devices.
