ABSTRACT:
A short-circuit protective device for a motor-driven and generator-driven electrical machine fed by a pulse-controlled a.c. converter has reverse-parallel circuitry that is switching dependent on a monitoring device. The monitoring device detects short circuits and is provided in a d.c. current supply line. Using the reverse-parallel circuitry and the monitor, an intermediate circuit capacitor of the pulse-controlled a.c. converter feeding the machine is isolated from the short circuit location.
