An Auto-triggered Crowbar Circuit

This paper introduces the functioning of crow ba r circuit and its realization method, introduces different kinds of crowbar cir cuit and different working mode. On the basis of experiment, we analyze the prin ciple of different kinds of crowbar circuit, compare the characteristics of diff erent kinds of working mode, and put forward a new auto-triggered crowbar circu it, which has advantages of simplicity, reliability, short delay time, small siz e etc. This circuit can reduce the breathed energy into transmitter tube.
