Abstract
A protection circuit for producing one or more triggers in the presence of a monitored overvoltage condition employing a complex voltage divider network including slow-acting breakover semiconductor devices for sensing ac voltage overloads in either or both polarities thereof, and operating gated semiconductors by controlling the voltages applied to both the gates and the main terminals thereof, which, in turn, discharge capacitors for trigger production. Monitoring may be with respect to supply voltage, power supply output voltage or one or more independent voltages.
