example, CRAMP could be clamped via an opto-coupler device to limit the short circuit current.
If a short circuit occurs during normal operation, the voltage dip comparator resets the
ramp, limiting the short circuit current within less than half a cycle. The ramp will then increase
again, until the line fuses blow or other action is taken.
The short circuit condition is signified by a train of 1-phase loss pulses, accompanied by
essentially zero bus voltage.
Externally controlled shutdown of the rectifier
The circuit in Figure 14 can be used, if desired, to externally clamp the ramp voltage,
hence also the output voltage of the rectifier, to zero.
