By knowing the architecture of a power supply's overvoltage crowbar circuit and its applications, you can easily apply and fully utilize this feature for many applications I need to dimension an SCR crowbar circuit to reach a certain level of protection against overvoltage, without increasing much the complexity of the circuit of my control card. The need is to protect a control card, which is powered through a standard AC/DC power adapter, from the risk of connecting the wrong power supply with higher voltage. The control card runs at 12V and draws circa 12A. This circuit adds a crowbar to Radio Shack's 10 amp, 13.8 volt power supply (#22-506). The Radio Shack design provides no protection should the pass transistor, a 2N3772, short out, a fairly common occurrence. This failure will put the power supply's reservoir voltage, nearly 24 volts, on the output terminals - not a good thing for devices expecting 13.8 volts! This shortcoming of the power. The overvoltage caused television sets to catch fire and were thrown out the front doors, exploded light bulbs, fried computers, destroyed surge protectors, blew up the Smart meters, and sparks shot out of wall outlets. The overvoltage only ended when the Smart meters blew up, or after 90 minutes when the power was physically cut. The incident was not reported by PG&E to the California PUC.

Bench Comparison of Two Overvoltage Protection (Crowbar

The circuit is called a crowbar as its action is about as subtle as a swift blow with a crowbar. Such circuits may often be found preventing power supply circuits from outputting a higher than normal voltage under fault conditions. The basic idea is that if, for example a fault in a DC power supply line causes the output to rise above its specified voltage value, this 'over voltage' is sensed. While Elecraft assures me that the K3 can survive an overvoltage with minimal damage, I prefer to be on the safe side. So I designed a crowbar circuit, which can be used with any 12 V power supply up to 30A. If the voltage exceeds the trip point (14-16 V), it will short the power supply output and, if necessary, blow a fuse
