Crowbar Protection Circuit. The crowbar circuit mechanism contains crowbar device and sensing circuit monitoring circuit. It operates by putting a short circuit low resistance path across the output of the psu.
It consists of thyristor of a rating well in higher than the rating of the devices that are to be protected. The zener is chosen to be slightly higher. On detection of the fault crowbar thyristor is fired consequently fuse blows.
Once triggered they depend on th.
In this case 15v. In this case 15v. A crowbar circuit is different from other safety or latching circuits for example a clamp in pulling. Crowbar circuits are frequently implemented using a thyristor triac trisil or thyratron as the shorting device.
